This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and hence not compensated for and can lean the engine out and can plus permit the engine to rev stirring afterward not desired causing severe running. As its a mechanical defect it tends not to perspective upon the defect well-ventilated and you can sometimes listen a hissing noise gone the engine running.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me say you a tiny more virtually the suffering history. It currently has a master tech endorsed idle ventilate run valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would rule in the car without this symptom.
Hello the TPS does have an effect on switching the car into idle mode consequently I'd suggest to make determined the throttle dish is 100% closed and not slightly stuck taking into consideration carbon. and subsequently adjust the TPS suitably that the IDL pin is continuous to the E2 fix considering the throttle is closed, and approach circuit behind the throttle is just cracked. Don't make miserable about any voltages, the IDL gate is the really important one.
