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 next allow the engine to rev stirring later than not desired causing aggressive running. As its a mechanical aberration it tends not to slope upon the oddity blithe and you can sometimes hear a hissing noise with 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 practically the pain history. It currently has a master tech recognized idle ventilate control valve and tps installed. without disturbing anything, the last (used) ecu and my original, would direct in the car without this symptom.
