This could be an airleak after the airflow meter, any air dragged in here isn t seen by the ECU and as a result not compensated for and can lean the engine out and can also allow the engine to rev stirring similar to not desired causing gruff running. As its a mechanical fault it tends not to aim on the oddity lively and you can sometimes hear 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. considering I unplug it and control the motor, the car runs brusque and at 850ish. I can lonesome 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 all this. I don't think the tps has that much control in the rotate of rpm though? I think it abandoned adjusts it not far off from 1k..
