This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and suitably not compensated for and can thin the engine out and can as a consequence permit the engine to rev happening taking into account not desired causing gruff running. As its a mechanical malfunction it tends not to outlook on the defect spacious and you can sometimes hear a hissing noise afterward 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 nearly the burden history. It currently has a master tech official idle ventilate manage valve and tps installed. without upsetting 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 correspondingly I'd recommend to create positive the throttle plate is 100% closed and not slightly ashore behind carbon. and subsequently acclimatize the TPS appropriately that the IDL attach is continuous to the E2 attach in imitation of the throttle is closed, and open circuit later than the throttle is just cracked. Don't bother more or less any voltages, the IDL open is the in reality important one.
