AC on/off voltage is correct on ECU pin 14. Have tried three other ECUs - high idle fault persists. Throttle body - I cannot fault. Disconnected and plugged manifold, brake booster hose and aux vacuum hose - fault persists. I have observed that when the idle valve is plugged, idle drops to 600 rpm and then slowly rises to 900 rpm. is this normal? Is it the ECU compensating or is this telling me something?
