This could be an airleak after the airflow meter, any ventilate dragged in here isn t seen by the ECU and so not compensated for and can lean the engine out and can afterward permit the engine to rev stirring past not desired causing argumentative running. As its a mechanical fault it tends not to twist on the deviation open and you can sometimes listen a hissing noise subsequently the engine running.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me tell you a tiny more approximately the hardship history. It currently has a master tech endorsed idle expose control valve and tps installed. without moving anything, the last (used) ecu and my original, would govern in the car without this symptom.
Hello the TPS does have an effect on switching the car into idle mode suitably I'd suggest to create clear the throttle dish is 100% closed and not slightly stranded in the same way as carbon. and subsequently adjust the TPS consequently that the IDL attach is continuous to the E2 glue later than the throttle is closed, and right of entry circuit considering the throttle is just cracked. Don't make miserable nearly any voltages, the IDL entrance is the really important one.
