STALLING PROBLEMS

pull codes.
it could be many things. one to keep an eye out for (and check values for):
the ECT and ACT sensors. since you have problems cold, check the cold and warm values for these two sensors. one or both may test within spec, but be incorrect for the situation. i.e. the sensor thinks the car is warm, and leans out (causing stalling when cold), but is actually the correct value for a WARM motor (thus not pitching a code).

good luck.

Hehe, my trouble is the oppposite!!!

With the advent of th 90 degree weather, my car is stalling at idle under load (like dropping into reverse) when I first start it again after driving it and shutting it off for a few minutes or so. Drivin me nuts... No codes either... sigh...
