I have a 2.5 cutlass vehicle runs mormal when cold. When vehicle is warm starts normal but stall when put in gear. I can put it in gear and drive when its warm if I put my foot on gas and brake at the same time and keep the rpm's up. I have changed the t p s and when I tapped the maf sonsor there was no differance in the way the motor ran, could this be the iac help me out please.

Yes that is most likely the problem. I would clean the throttle body and the IAC.

There you go. Hopefully thats it, when it heats up it acts up. Nine times out of ten the crank sensor will not create a check engine light

Ok, clean the throttle body and clean the iac and or replace it. If there is a check engine light on now, scan it and let me know what the codes are.
