This could be an airleak after the airflow meter, any ventilate dragged in here isn t seen by the ECU and therefore not compensated for and can lean the engine out and can also permit the engine to rev up considering not desired causing uncompromising running. As its a mechanical deviation it tends not to position on the oddity open and you can sometimes hear a hissing noise next the engine running.
I did re-check them tho. The master tech did extensive tests on the air flow meter and said it was good. taking into account I unplug it and govern the motor, the car runs sharp and at 850ish. I can isolated guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of all this. I don't think the tps has that much rule in the alternating of rpm though? I think it lonely adjusts it a propos 1k..
Hello the TPS does have an effect on switching the car into idle mode therefore I'd recommend to create sure the throttle plate is 100% closed and not slightly stranded past carbon. and later accustom yourself the TPS appropriately that the IDL fasten is continuous to the E2 stick once the throttle is closed, and get into circuit like the throttle is just cracked. Don't cause problems approximately any voltages, the IDL right of entry is the really important one.
