Have a 98 GS-T and when ever car sits for a while or when I go to start in the mourning it will studder and die, almost like it's carburated. I have to rev it up for a minute and when I move, it will studder like a mother fucker.

I've cleaned the throttle. I dont see any lines open but I could be over looking. Was woundering if any body had any advise for me on what could be the problem. Could it be a sensor or dirty injectors.


Thanx

 

anything done to the car?

 

but then when it worms up it is fine?When it started doing this,how long ago?

 

Ya it runs fine after it warms up. Its been doing it for more than 5 months


I only have intake exhaust and a 1st gen turbo done.

 

do the basics check for loose lines and all. if u have a bov make sure thats tight. and there are no leaks.

 

I checked for loose lines, didnt see any. BOV tightened down no air leeks that I can see

 

try replacing your fuel filter

 

yea,try fuel filter and won't hurt if u check ur fuel preasure,see if it is strong enough.It is not a leak cuz if it is,it would do it all the time,but in his case it does it only when cold,so check ur fuel sistem.My camry does same shit and it is cuz of my fuel pump.I have to have 28 psi but my pump suplay 25-26 i duno why and every time i start the car I have to keep the gas pedal down for a few sec or the car will just turn off.Then when it worms up it is fine.Check it and post results.

 

IT may also be an O2 sensor malfunctioning. Those usually tend to go out around the 60,000 mile mark, earlier or later, give or take. It may not flag a CEL right away either. I had symptoms similar to what you are having and found that my heated O2 sensor was the problem. You may also want to check your charcoal canister too and see if that needs to be replaced. Those usually don't need to be replaced, but they will if your car is running rich. When you start your car up and let it warm up for a while, can you smell fuel fumes emitting fromt he car when you are standing next to it? If so, then the charcoal canister is full.

 

when i was forced to remove my AFC i forgot to put my honeycombs back in and the car started like ASS. I put them in and everything was fine again. Just my .02
