well, the stag is stalling. i'm presuming that its an AT issue primarily because when the car is warm (seems to run completely fine on cold start and idle in neutral is fine and steady), i start to get issues when slowing to a stop - engine revs drop RIGHT down, as though trans isn't dropping down gears? once these games have begun it stalls intermitently during accellerating when it need to shift up as well. engine revs drop right off to nothing, though it will intermittently pick up again as though the trans catches like when you jump start a manual. it's been doing this for a couple of weeks now because i've not had the cash to get it sorted. went to have it looked at the other day and was told it was the fuel filter being block up which while understandable why they thought that, doesn't ring right with me.

so i've got a couple of questions:

1. does my diagnosis seem reasonable? if you need more info before you can say yay or nay, let me know.

2. does anyone know of a reputable auto trans servicing centre they can recommend in perth?

or does anyone have a consult cable and software than can read the fault codes for me?

cheers,

Dave.

yeah mine did that when i put the breaks on also, would just about stall.

i had a transmission gasket leak. loss i pressure i put it down to.

now im up for a rebuild LOL ! take it to any trans workshop who can hook it up to there comp, or nissan dealer best bet. dont leave it too long. left mine for about 12,000km's and got the worst result hehe :P

all the best dude

do you still have your standard BOV in place? have you blocked it or removed/replaced it?

yep she's still a complete stocker apart from the almost mandatory stereo upgrade. why's that?

yowsers - i'll be a little pissed if i'm up for a rebuilt only 8months after buying it :/

any idea of ball parks prices i'd be looking at for an AT service?

hmm my M35's been doing that lately. i've been questioning the transmission ever since i bought it...

Had the trans serviced only 2-3 months ago though...so hopefully its not the trans for me...i think mine's more related to steering somehow...but anyway.

If you don't know how long it's been since it has had a replacement fuel filter, I would at least just do it for the sake of it. They are inexpensive and as far as i am aware, look pretty straight forward to do as it is nice and accessible in the engine bay.

had this done the other day, no difference - stalled about 200m up the road from the service place. initially i thought it was related to my p/steering as well, however had steering pump fixed at the same time, still stalling. have done some additional searching and people have been having the same prob tracked back to various sensors such as engine temp and air flow meter. will have a look in fast tonight when i get home to see about replacing them

not sure if it will fix your problem but reset the ecu by disconnecting the battery, pressing the brake pedal a couple of times and leaving the car for half hour or so. then come back and connect it up again and let the ecu start fresh :/

ball park figure for a service ... $150 . . .

i only owned mine for about 8months i think. previous owner had it for 11months (finacial problems, nice guy)

i just got the ticking time bomb, car's done 107,000kms now, got it at 84,000 if those numbers match up, get the service kit done, that ways its open for a reason, get them to do some ECU testing, in one hit

If it were just under braking i would have thought your brake booster has a vacuum leak but if its playing up shifiting upwards through gears you could be in dramas. A service never hurts - its something that should be done routinely anyway so may as well do it and if it fixes your problem then sweet.

Definitely sounds like a leak tho. Did you try the ECU flash...?

Sounds reasonable buddy...loss of fuel would deffinatly do this, and seams its not an expensive thing to replace a fuel filter try it first. If it doesn't work at least you've got a clean fuel filter in.

But on the other hand does the M35 run a accelerator cable or is it electronicaly controlled?

My mates BA ute(ford) is having similar probs at the moment. The mechanic thought it was the throtle possision sensor/swithch. Just another idea.

Hope i'm not confusing things by what I posted. I think the original post was about a series 1 stag. Mine is an M35 and I'm not 100% sure but I dont think it has a fuel filter. It does have drive-by-wire though. The s1 stag has a fuel filter but not electronic throttle.

mine's due for a service sometime so will just get it looked at then.

I solved my M35 stalling problem by having the TPS (throttle position switch) reset. I am not sure if this will help you but it did stop the stalling. It does now idle about 100rpm higher than I would like but it is better than stalling every I pulled up quickly. It now idles around 800 - 850 rpm in neutral and it is meant to be 750 rpm.

To reset the TPS it is just a sequence of turning the ignition on and off with minimum time for each part.

1) turn ignition on for at least 2 second.

2) turn ignition off for at least 10 seconds.

3) turn ignition on for at least 2 seconds.

4) turn ignotion off for at least 10 seconds.

this is meant to reset the TPS.

I think the stalling may be slightly to do with the TPS but I suspect it is also to do with either the O2 sensor or the spark plugs. This is not a definate answer but it is my gut feeling.

Cheers

Andy

Awesome!! Hopefully this works for me. I didn't realise there was such a way to do this...

Mine idles on 500rpm (no kidding) sometimes less but the needle wont show much below 500rpm - and about 600-700rpm with a/c on. I know it should be higher than this and it doesn't just affect idle, it feels a bit dead sometimes when just cruising along - like it just drops out until i touch the accelerator again.

The other thing it affects is that it rolls backwards if i'm on an upward incline and i lift my foot off the accelerator. normally auto's shouldn't do this but ours does and its a bit disconcerting :S

Hopefully this is a simple fix otherwise I've thought maybe I need to get the idle adjusted (can you do that?).

Its really only started stalling lately - and only with a/c off (a/c lifts the revs a bit you see) so I'm pretty certain its just something simple like the above. Will let you know what happens...

Other suspicions i have are air-flow meter or spark plugs (no idea what they used in compliance).

There is no way to adjust the idle speed. It is all done from the TPS and the computer.

Try and look for the G35 service manual on line. Lots of useful information that relates to our cars.

I've tried resetting the TPS like you said, and I've also cleaned the AFM and reset the ECU (disconnected battery), but its still doing the same thing. Drives fine out on the road but when idling it seems to drop really low then quickly steady itself at 500rpm, where it doesn't feel smooth since its idling too low. It does make the steering harder too when its revving this low.

Will check the manual but its looking like a faulty TPS or something like that. Any way to check ECU fault codes by myself? or do I need to take it to Nissan (or someone with a consult cable & software) to do that?

I knew a lot more about my old stagea (series 2) but with this one I'm having to start over...learning it all again.

You mentioned that you were not sure what they did with plugs at compliance. The standard plugs for these cars are Platinum or something similar and are good for 80-100k km.

I have been reading about the Blatz, IBDII software and cable and from what I have read, although there is a lot more to read, it should help with the fault codes and allow you to reset them. At about $200 bucks it sounds like a good investment.

http://www.blazt.biz/index.php

I have also listed below the info from the manual. Some of this may help.

Accelerator Pedal Released Position Learning ABS0003L

DESCRIPTION

“Accelerator Pedal Released Position Learning” is an operation to learn the fully released position of the accelerator

pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time

harness connector of accelerator pedal position sensor or ECM is disconnected.

OPERATION PROCEDURE

1. Make sure that accelerator pedal is fully released.

2. Turn ignition switch “ON” and wait at least 2 seconds.

3. Turn ignition switch “OFF” wait at least 10 seconds.

4. Turn ignition switch “ON” and wait at least 2 seconds.

5. Turn ignition switch “OFF” wait at least 10 seconds.

Throttle Valve Closed Position Learning ABS0003M

DESCRIPTION

“Throttle Valve Closed Position Learning” is an operation to learn the fully closed position of the throttle valve

by monitoring the throttle position sensor output signal. It must be performed each time harness connector of

electric throttle control actuator or ECM is disconnected.

OPERATION PROCEDURE

1. Make sure that accelerator pedal is fully released.

2. Turn ignition switch “ON”.

3. Turn ignition switch “OFF” wait at least 10 seconds.

Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.

Cheers

Andy

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
