This could be an airleak after the airflow meter, any expose dragged in here isn t seen by the ECU and consequently not compensated for and can lean the engine out and can after that allow the engine to rev happening in the same way as not desired causing rough running. As its a mechanical aberration it tends not to point of view upon the malfunction light and you can sometimes listen a hissing noise like the engine running.

I did re-check them tho. The master tech did extensive tests upon the air flow meter and said it was good. like I unplug it and govern the motor, the car runs uncompromising and at 850ish. I can on your own guess that my supplementary 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 control in the exchange of rpm though? I think it single-handedly adjusts it with reference to 1k..
Hello the TPS does have an effect upon switching the car into idle mode in view of that I'd suggest to create sure the throttle plate is 100% closed and not slightly ashore behind carbon. and subsequently familiarize the TPS fittingly that the IDL pin is continuous to the E2 pin next the throttle is closed, and right to use circuit gone the throttle is just cracked. Don't badly affect roughly any voltages, the IDL entre is the in fact important one.
