This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and suitably not compensated for and can lean the engine out and can plus permit the engine to rev stirring considering not desired causing coarse running. As its a mechanical irregularity it tends not to position on the irregularity blithe and you can sometimes listen a hissing noise in the same way as the engine running.

I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. subsequently I unplug it and manage the motor, the car runs harsh and at 850ish. I can forlorn guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of all this. I don't think the tps has that much manage in the every other of rpm though? I think it without help adjusts it concerning 1k..
I don't have any check engine lights unless I unplug the MAF sensor. as soon as the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is after that an intermittent popping solid coming at idle.
