R32 gtst hot issues

Hey,

So ive got a 1992 gtst type m that i picked up recently. Its got 100,540km on it now and i just did the timing belt, put on a cheap diy intake and thats it. The car is in spotless condition.

Now im having an issue with the car when it warms up. Originally it would just start hard after the car had been driven. Now the car will start fine cold with no misfires or anything, but as soon as it gets to operating temp it just stalls. If you crank it over the idle will be high, around 1800rpm and then it will start to idle hunt from about 800 to 1800rpm. If you give it any throttle input itll stop at 2500 rpm which im assuming its a limp mode?

I replaced the ignitor and checked all fuses throughout, but im running out of ideas. 

Any help would be appreciated!

Small update.

I unplugged the MAF while it was idle hunting and when i plugged it back in the idle INSTANTLY dropped back to normal and the car stopped running in limp mode.

So now the car is back to starting hard after its warmed up. Itll start up but immediately die. Then it takes 10 to 15 seconds of cranking before it sort of "coughs" to life and then runs perfect again.

Well i still have the factory parts and i may put it back to stock. That being said when i got the car the MAF wasnt tightened down in the inlet tube. Its a super tight fit even getting to the clamp which might be why it wasnt done up properly.

As far as i can tell this car was dealer maintained its whole life.

Ordered a used maf hopefully itll help with my issues. Also going to pull my stocker apart and see how bad it is.

Reading through a few posts scattered across the net, some people said the contact points in the connector have fallen apart due to time and heat among other things.

  • 1 month later...

So the idle hunt and other issues were solved with a remanned afm but im still having hot start issues.

In the morning the car fires up fine but getting in after work the car will fire up and the immediately die. Then the engine will crank for 5 to 10 seconds before it fires up. Today i noticed smoke from the exhaust and it appeared to be black. Ive also smelled fuel when the car needs to crank longer.

Is it possibly leaking injectors maybe?

    • 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).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
