This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and in view of that not compensated for and can lean the engine out and can in addition to allow the engine to rev occurring next not desired causing harsh running. As its a mechanical fault it tends not to point on the deformity lighthearted and you can sometimes hear a hissing noise taking into account the engine running.
I did re-check them tho. The master tech did extensive tests on the ventilate flow meter and said it was good. later than I unplug it and direct the motor, the car runs rough and at 850ish. I can only guess that my supplementary rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of all this. I don't think the tps has that much rule in the oscillate of rpm though? I think it lonely adjusts it approaching 1k..
