If I place my '94 LWB EFI 4.2L V8 RR Classic into neutral while coasting at low speed, The tachometer shows that the engine is bouncing between 1300 to 1600 RPM's back and forth erratically. If I unplug the connection to the Air idle control motor, the engine idles at 3,000 RPMs.
The Air Idle Control Stepper motor was replaced not too long ago. The O2 sensors have been replaced as well. My electronic traction control light is on. I dont know if that is related to this problem or not. Anyone ever see this?
