This could be an airleak after the airflow meter, any ventilate dragged in here isn t seen by the ECU and thus not compensated for and can lean the engine out and can moreover allow the engine to rev occurring past not desired causing sharp running. As its a mechanical irregularity it tends not to slant upon the defect blithe and you can sometimes listen a hissing noise behind 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. later I unplug it and run the motor, the car runs harsh and at 850ish. I can and no-one else guess that my new 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 every second of rpm though? I think it abandoned adjusts it a propos 1k..
Hello the TPS does have an effect on switching the car into idle mode correspondingly I'd suggest to create positive the throttle plate is 100% closed and not slightly high and dry similar to carbon. and later adapt the TPS therefore that the IDL pin is continuous to the E2 fasten following the throttle is closed, and read circuit afterward the throttle is just cracked. Don't trouble approximately any voltages, the IDL log on is the really important one.
