Not all the time, but sometimes when he puts it in drive,the car stalls. It's idling at the proper rpm and works fine other than that. And sometimes when he comes to a stop,it will stall. This morning he backed up traffic at a light because it stalled on him.When he started it, it stalled every time he put it in gear until he finally just revved the engine around two grand and then put it in gear.What could the problem be? Would this be an engine/sensor problem? Or should I post this in the tranny/drivetrain section?

 

Clean the IAC passage with carb cleaner, and adjust minimum idle and then adjust tps

 

Thanks Pablo. I'll tell my brother and see how that works.
