This could be an airleak after the airflow meter, any expose dragged in here isn t seen by the ECU and therefore not compensated for and can thin the engine out and can moreover permit the engine to rev stirring subsequently not desired causing severe running. As its a mechanical irregularity it tends not to slope on the defect vivacious and you can sometimes hear a hissing noise next 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 little more about the pain history. It currently has a master tech approved idle freshen rule valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would run in the car without this symptom.
Hello the TPS does have an effect on switching the car into idle mode therefore I'd recommend to make certain the throttle dish is 100% closed and not slightly grounded once carbon. and next adapt the TPS suitably that the IDL fasten is continuous to the E2 pin as soon as the throttle is closed, and admission circuit past the throttle is just cracked. Don't distress practically any voltages, the IDL open is the in fact important one.
