This could be an airleak after the airflow meter, any air dragged in here isn t seen by the ECU and fittingly not compensated for and can lean the engine out and can moreover allow the engine to rev in the works subsequently not desired causing aggressive running. As its a mechanical malformation it tends not to slope upon the deviation light and you can sometimes hear a hissing noise similar to 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 tiny more roughly the difficulty history. It currently has a master tech recognized idle expose manage valve and tps installed. without moving anything, the last (used) ecu and my original, would rule in the car without this symptom.
I don't have any check engine lights unless I unplug the MAF sensor. in the same way as the MAF is plugged in next the car will stall unless I put my foot upon the accelerator. There is along with an intermittent popping sealed coming at idle.
