after about 20 minutes of warm up the car begines to stumble/stutter, it seems as if it could be an electrical problem though i am unsure. i was just wondering if anybody could give me an educated guess on the matter. it had replacement engine and turbos installed aftr 50k and is now 20k into the replacement parts. it is a desert car its whole life, let me know thanks guys

 

We need more info on the car.

ANy mods?

What have you touched so far/previous to this problem?

Does this problem happen when cold?

Just by reading your post, i can throw out a guess and say its a TPS problem but even your problem is vague.

You need to elaborate more on everything.

 

Under what conditions does it stutter/stumble?

 

wat are your rpms reading? are they jumping up and down

 

no the car idles fine, it happens all the time but it starts after about 20 minutes of just sitting to wearm up. i havent touched the car, its stock execpt suspension. the engine an turbos were replaced 20k miles ago. does this help any

 

what sort of rpm fluctuations are you getting?

 

none really
