This could be an airleak after the airflow meter, any ventilate dragged in here isn t seen by the ECU and correspondingly not compensated for and can lean the engine out and can then allow the engine to rev taking place later not desired causing harsh running. As its a mechanical fault it tends not to face upon the malfunction light and you can sometimes listen 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 roughly the misfortune history. It currently has a master tech official idle air direct valve and tps installed. without distressing 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 as a result I'd suggest to make clear the throttle dish is 100% closed and not slightly ashore considering carbon. and next acclimatize the TPS in view of that that the IDL glue is continuous to the E2 attach past the throttle is closed, and contact circuit like the throttle is just cracked. Don't make miserable roughly any voltages, the IDL retrieve is the really important one.
