Surging RPM
At idol and also throughout the RPM's I have surging RPM's resulting in a stall &/or loss of power.
What could it be? O2 sensor? Knock sensor? How do I test it?
Please help. :confused:

Re: Surging RPM (65Z01)
Surging is ofter due to a vacuum leak, dirty throttle plates/body or dirty/failed IAC.
Mine was a bad plug wire. Check all the wires.
