help 94 zj stalling when warmed up
To start out the temperature in the car never gets that hot (maybe around 150ish) but as it starts to warm up it wants to stall under load like accelerating from a stop it hesistates, when coming to a stop letting off the acceleration RPMs drop very low. Sometimes, it will kick back up to idle other times it dies. I have changed the TPS, IAC, and map sensor. After start up while cold jeep runs good no problems until driving for awhile, enough time for the motor to warm up but still Idles good and starts right up after stall. seems to be worst in hot weather

did you ever find out the issue? this sounds like what mine is doing. was told it was a crank position sensor but I want to be sure before replacing it

Chances are it is the PCM module. They are known for causing issues when warmed up or extremely cold.
