Got a 96 Grnd Cherokee lorado, my problem is that when i am at a complete stop my RPM go down as if the car wants to turn off. I change the spark plugs and wire, gas filter, stander throttle position sensor, and the IAC motor and it is still giving me the same problem. I do not know what else to do. I took it to a mechanic to check it out and it seemed like he had no idea what was going on. Can anyone help me.
Again problems,
RPM go down when at complete stop when on Drive. car is fine when on (N) or (P). Also when on road rpm increase and then go back down to normal.
