This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and suitably not compensated for and can lean the engine out and can next permit the engine to rev taking place in the manner of not desired causing severe running. As its a mechanical anomaly it tends not to tilt upon the aberration roomy and you can sometimes hear a hissing noise like 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. as soon as I unplug it and rule the motor, the car runs scratchy and at 850ish. I can only guess that my extra 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 oscillate of rpm though? I think it on your own adjusts it with reference to 1k..
I don't have any check engine lights unless I unplug the MAF sensor. later the MAF is plugged in next the car will stall unless I put my foot upon the accelerator. There is moreover an intermittent popping strong coming at idle.
