An NGS not hooked up could cause a high/hanging idle.
My car doesn’t have it hooked to the trans but it’s hooked on the clutch pedal. If I slow down and slip the trans out of gear wen not under load, the idle will hang until I press the clutch pedal in
Clutch pedal and trans NGS are wires in parallel
so i don’t need to worry about the transmission sensor as long as the clutch pedal one is hooked up?
