This could be an airleak after the airflow meter, any air dragged in here isn t seen by the ECU and for that reason not compensated for and can thin the engine out and can in addition to permit the engine to rev occurring gone not desired causing aggressive running. As its a mechanical anomaly it tends not to aim on the defect lively and you can sometimes hear a hissing noise with the engine running.
I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. like I unplug it and run the motor, the car runs harsh and at 850ish. I can unaided guess that my additional rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don't think the tps has that much run in the exchange of rpm though? I think it solitary adjusts it approaching 1k..
I don't have any check engine lights unless I unplug the MAF sensor. later the MAF is plugged in subsequently the car will stall unless I put my foot on the accelerator. There is afterward an intermittent popping hermetic coming at idle.
