This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and in view of that not compensated for and can thin the engine out and can afterward allow the engine to rev happening behind not desired causing rasping running. As its a mechanical fault it tends not to slant upon the idiosyncrasy blithe and you can sometimes hear a hissing noise past 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 difficulty history. It currently has a master tech qualified idle let breathe run valve and tps installed. without heartwarming 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 for that reason I'd suggest to make determined the throttle plate is 100% closed and not slightly beached in imitation of carbon. and subsequently acclimatize the TPS fittingly that the IDL fasten is continuous to the E2 pin following the throttle is closed, and edit circuit past the throttle is just cracked. Don't bother just about any voltages, the IDL entrance is the in fact important one.
