Ok. Thks. So what do i need to clean if the engine stalls and dies; no check engine light and no codes?
From my internet reading everything was pointing to IAC??

When does it stall and die? On cold start only, or all the time?

Sometimes when the engine is first started after about 5-10 minutes. Other times at intersections. Car is not stalling down the road, etc. It just dies randomly

If you have access to a decent scan tool you can monitor STFT and LTFT and see if the engine is running lean. It may not be bad enough (yet) to set a code, but monitoring the STFT and LTFT will give you a idea of what is going on.
