Been having a high idle problem lately on my ef falcon the car is idling at 2500 rpm i have tried replacing the idle control valve i used a au 1 as i had a spare one laying around i have tried replacing my map sensor as when i unplug the sensor it stops idling so high but that has not seem stop the high idling problem.
I Have done a manual conversion and trick the ecu with the resisters.
