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 in addition to permit the engine to rev occurring taking into consideration not desired causing gruff running. As its a mechanical idiosyncrasy it tends not to direction upon the irregularity lighthearted and you can sometimes hear a hissing noise in imitation of 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. later than I unplug it and manage the motor, the car runs rough and at 850ish. I can lonely guess that my additional 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 direct in the vary of rpm though? I think it solitary adjusts it just about 1k..
Hello the TPS does have an effect upon switching the car into idle mode therefore I'd recommend to make positive the throttle dish is 100% closed and not slightly stuck gone carbon. and after that get used to the TPS consequently that the IDL fix is continuous to the E2 fasten similar to the throttle is closed, and read circuit next the throttle is just cracked. Don't worry nearly any voltages, the IDL admission is the essentially important one.
