This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and therefore not compensated for and can lean the engine out and can along with permit the engine to rev stirring when not desired causing rasping running. As its a mechanical deformity it tends not to turn on the idiosyncrasy light and you can sometimes hear a hissing noise later than the engine running.
I did re-check them tho. The master tech did extensive tests upon the let breathe flow meter and said it was good. following I unplug it and govern the motor, the car runs rasping and at 850ish. I can unaccompanied 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 substitute of rpm though? I think it single-handedly adjusts it vis--vis 1k..
