hey,

When driving my R32 GTR it keeps cutting out (similar feeling to running out of fuel) and when it does this it wont idle it just stalls, then ill start it again and it will idle ok and drive normally for a bit (seconds to a minute or so), then start cutting out again

the feeling when it cuts out at say 2500rpm is very similar to running out of fuel in your tank but a tiny bit different, runs really rough like its dropped half the cylinders and looses all the power completley. its not persistent tho and when it comes good it runs perfectley for a little while (enough to limp home on).

my guess is its a fueling issue of some sort, has anyone come across this problem before?

the ignitor module does look a little corroded on the outside, ill take a better look at it

Hey i got the same problem with my 33, but my one is from 3000 rpm travelling at an average st speed, pop it to neutral then the idle jst drops down as if its gonna stall then at one - three times it did stall, but wen i put it back to gear it started running again =S

i have an r32 89 rb20, and yes it is an auto. It had sort of the same prob. kept stalling on me, it still does. but yeah cruisin down the highway it would just cut out...and the kick back in and be fine. The other day it just kept stalling and when it would idle i would try and rev it, when it got to 2500 it would hit like a rev limiter and just back off..and then it would stall. So i would let it sit and it would be fine. But does that explain why it wouldnt do it all the time, and would it be why it does it when i am going down the highway??

EDIT: Someone suggested it could be the crank angle sensor....but the air flow meter sounds interesting....i reset my ecu and it was good for the rest of my trip, so that might be a temporary solution.

Hey i had that before, but i fixed it now, its really quite simple if you dnt know where to start. Firstly do you have an aftermarket BOV? Rev it to 4-5000 rpm then check if the engine is about to die, do it for a cpl of times. If this is the problem then jst swap ur stock bov then try it again if it doesnt fail its definitely your BOV.

It could be alot of things but i know the GTR's have a limp mode built in to the ecu programming. That will limit the revs to 2500 if sumthing is wrong...

Yeah man thats what my importer said. Yeah but sometimes it does not just limit the revs but like cuts out at the 2500. and sometimes it will limit it. I wiped my ecu and it still does it though. So has annoyone got any other ideas.

Lang: In simple mans terms, the loose wiring in the loom...where do i find the loom? :S

the loom is the wiring loom which afaik just means all the wires that go from the ecu to various parts of the engine bay, allthough i think in my case (a freind fixed it) it was to do with the wiring from the airflow meters to the ecu.

I have a very similar problem

the car stalls "randomly", especially after I hit bumps.

monday, I went slowly into gravel, turned the car off, started it, and went about. 15 secs after.. engine died and didn't start again after 5 tries, Fuel pump was priming so that wasn't the prob. I have a recirculation BOV so if it leaks, it goes in behind Z32 MAF. I tried following the wire loom from the connector and it passes right under the A/C oil canister... and the loom was somewhat filled with old oil.

I will for sure to to follow that cable tonight and make sure everything is secure and undamaged.

My car is not in limp mode, I can go to redline with no trouble and with quite a bit of power.. if it's not acting up hehe

I do hear misses at any rpm range... like Highway... at 3000 it will do it but for like 1/2 sec and the engine "starts" back. I will also clean the MAF tonight with electircal contact cleaner

and verify every air path :P

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
