This could be an airleak after the airflow meter, any ventilate dragged in here isn t seen by the ECU and hence not compensated for and can lean the engine out and can next permit the engine to rev occurring subsequent to not desired causing unfriendly running. As its a mechanical oddity it tends not to turn upon the irregularity blithe and you can sometimes hear a hissing noise following the engine running.
I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. with I unplug it and run the motor, the car runs sharp and at 850ish. I can unaided guess that my other 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 rule in the alternative of rpm though? I think it and no-one else adjusts it nearly 1k..
I don't have any check engine lights unless I unplug the MAF sensor. bearing in mind the MAF is plugged in subsequently the car will stall unless I put my foot on the accelerator. There is moreover an intermittent popping sealed coming at idle.
