my car stalls when goming to a slow stop but not at a hard stop. the traction control will not trun on until the engine hit 180 F. Engine light turns on and off but no code is registered. rough idle with no lad but with the a/c it does fine


WHAT IS WRONG :? :?

How is your spark wire and plugs? Ever had your injectors/fuel system cleaned, even with a bottle of additives?

Have you actually tried to run a diagnostic on your computer? It wont show some errors that the computer has found with your SES light.

well i went to the gm dealer and they didn't know what was wrong the ses light was on but with no codes showing and yes a diagnostic was done with no answers amd its is sill salling what the hell is wrong :?

oh and it sill stalls when the a/c is but only whenthe engine is hot

It sounds like one of those tough problems. I like the idea of the IAC valve, because if you come to a slow stop, it may not need to respond as fast, and it may be getting stuck in there with some sticky stuff.

were is the iac valve and the fuel mix is to high you can smell it after coming to a stop when it doesn't stall on me

Before you replace the IAC valve, you should take it out of the throttle body and clean its passageway along with the rest of the throttle body. Can't guarantee this will solve the problem, but it is a good tune-up place to start. Remember this could be a whole slew of tune-up related items.

The IAC valve sits on the bottom of the throttle body, above the throttle position sensor. The best way to test it is with a Tech 1.

I'm not having any probs, at least now, but was thinking of getting a tune-up. However, I have new plugs, new wires, PCV, ... A lot of the "tune-up package" the shop has here I have already solved. At least most of it I think. Except for cleaning the TB. Is this something that can be done easily??? Would I have to take it off?? (Yeah that'* probably a dumb question. Sorry) Just don't want to pay someone just to clean the TB.

What else is typically done in a tune-up? Thanks

well i am taking out the iac and what is a tech 1

Make sure you clean the passageway where it sits if you are taking it out.

A Tech 1 is the computer that the mechanics and dealer use to communicate with your car'* computer. It can be used to manually override the computer and increase idle speed by opening up the IAC valve.
