:D Hey guys, since buying the R32 gts-t about a month now i seem to be encountering a few problems.

#1 seem to crank the car more than once to get it to turn over,if i crank it once and give it a lil foot on the

gas it will start fine. If i don't give it a foot it will shake and jerk then stalk without the engine even starting

up yet. When i hear the sound & running of the fan thats what im refering to when i say engine not starting up

yet.

#2 The car seem to run good every so often,but when it stalls on you like this it gives u the shits.It will stall at

red lights, stalls while the turbo timer is running even stalks sometimes when im driving. Most of the times i

feel it in my gear down shifting,gears doesn't feel like its been down shifted and when i come to a stop then

looking at my rpm its reading way over the 1000rpm mark, then splat the car stalls. The revs will go pass

1000rpm then drop down and stalk. Down shifting gears is suppose to feel like the car is slowing down and

u can hear the engine doing that, When the revs is high and im down shifting i don't hear that, come to idle

at red light if revs over 1000rpm it will drop then stall.

#3 Why is my car jerking alot now . The car seem to jerk alot when i give it. I ease off the gas and try again it will

jerk. Jerk violently sometimes. The other night i wanted to give it so i down shift to 4th the car didn't go

nowhere,the revs didn't move.So i couldnt even down shift to see how the car would go.Felt like

some kind of blockage. Could it be something to do with the sparkies i just put in. I've read about how you

suppose to regap them,but not to sure if it is the sparkies.

Yeh sorry guys for blabing on,i apologies but i do need some help . If anyone could help out that would be

great.thankz guys

#1 is a common problem. A lot of R32 owners have the same cold start problem (including my self)

Clean your aac valve to see if this fixes your idling rpm.

Also do you have a blow-off value? Have heard this causes issues on idling too.

1 - it seems that most 32's have the same cold start issue. mine included, you learn to live with it after a while. cleaning the aac valve and iac valve helps

2 - like others have said it's probably the afm dying. if you have an atmo bov that could be causing the problem too. get a std bov and see if that fixes it

3 - could be your afm again, could be your coilpacks. is it misfiring (exhaust making popcorn noises)? whats your spark plug gap? it could be an air leak. Check your intercooler and turbo piping for any leaks, make sure the hose clamps are tight and the pipes/hoses firmly seated.

My car used to jerk + misfire etc on boost but drove around fine off boost, turned out to be the tiniest air leak from a slightly loose hose clamp that grew on boost but sealed off boost.

the revving over 1000rpm then stalling could be because the motor is opening the aac valve and raising the revs trying to compensate for air being lost somewhere but cant get enough so it stalls.

When its jerking is there alot of black smoke coming out of the exhaust?

the engine manual says idle should be set at 650rpm, but mines at around 800-900rpm.

apart from using more petrol at idle i dont see there being any problem with that

Yeah I think the jerking is some sort of boost issue. What boost is running? Also it could be a leak of one of the hoses etc as R32woohoo said or it could be a blocked wastegate etc.

Bottom line: that jerk indicates that the ECU is cutting boost in what it believes to be an emergency situation where the boost is climbing too rapidly for what the stock ECU thinks is installed in the car and is likely to blow a head gasket if it continues.

And if you're not overboosting then I think the ECU thinks you are/there is a flow problem that could be potentially major if it wasn;t cut off. Don't drive around with it continuing to do that, cutting off boost so immediately that the entire vehicle jerks violently CANNOT be good for your cars internals (just better than the alternative to the ECU).

Theres no such thing as boost cut. the ecu has no control over boost whatsoever.

If its an air leak it jerks because the air that was supposed to go into the cylinder for combustion has leaked out and the fuel cant ignite.

ie: the injectors are squirting but theres no air to burn it

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.

      RH9 R32 GTR Build Thread

      By OST Micah · Posted

      While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
