Starting engine problem

**Grandprix202** · 07-22-2013

In my 04 gt N/A it has an issue of starting ever since I've had it. But the word thing is is that it seems to start up nice and strong on cold starts but it can't "grab" and start up strong after being driven or warm starts. It turns over but I just need to give it gas to get it to start when it's warm. Any ideas on what this could be?

start out with cleaning the TB. remove it to clean it.

Alright...I'm not much of a mechanic so what exactly is the throttle body and where is it located

It has the rubber air intake tube connected to it.

Oh alright...is it hard to take apart and clean?

on that year you can clean it up pretty good left on the car, carb cleaner and a shop rag, take the air filter tube off, push that gold fliap open, then spray and wipe, behind the flap, and the outer wall, as well as the flap its self, on the back side and the edges.

you can see the black ring on the gold part in the pic posted, you want all that off and clean. it will be very black behind that flap.

04's are known for that not catching on the first start. GM has an updated calibration for it, but being its out of warranty you'd have to pay unless someone can flash your PCM.
