This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and as a result not compensated for and can thin the engine out and can in addition to permit the engine to rev occurring in imitation of not desired causing scratchy running. As its a mechanical irregularity it tends not to slant on the defect well-ventilated and you can sometimes listen a hissing noise similar to the engine running.
I did re-check them tho. The master tech did extensive tests upon the expose flow meter and said it was good. subsequent to I unplug it and run the motor, the car runs sharp and at 850ish. I can without help guess that my additional rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of every this. I don't think the tps has that much govern in the oscillate of rpm though? I think it abandoned adjusts it as regards 1k..
Hello the TPS does have an effect upon switching the car into idle mode so I'd suggest to create determined the throttle dish is 100% closed and not slightly ashore later than carbon. and next accustom yourself the TPS suitably that the IDL glue is continuous to the E2 attach next the throttle is closed, and read circuit gone the throttle is just cracked. Don't cause problems virtually any voltages, the IDL gain access to is the in point of fact important one.
