This could be an airleak after the airflow meter, any ventilate dragged in here isn t seen by the ECU and fittingly not compensated for and can thin the engine out and can next allow the engine to rev stirring with not desired causing uncompromising running. As its a mechanical defect it tends not to face upon the malfunction roomy and you can sometimes listen a hissing noise once 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 approximately the pain history. It currently has a master tech ascribed idle air manage valve and tps installed. without disturbing anything, the last (used) ecu and my original, would run in the car without this symptom.
Hello the TPS does have an effect upon switching the car into idle mode so I'd recommend to make sure the throttle dish is 100% closed and not slightly grounded afterward carbon. and later become accustomed the TPS in view of that that the IDL pin is continuous to the E2 fasten subsequently the throttle is closed, and entry circuit with the throttle is just cracked. Don't worry about any voltages, the IDL gain access to is the essentially important one.
