This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and consequently not compensated for and can thin the engine out and can in addition to allow the engine to rev happening in the manner of not desired causing prickly running. As its a mechanical irregularity it tends not to outlook on the idiosyncrasy lighthearted and you can sometimes listen a hissing noise as soon as the engine running.
I did re-check them tho. The master tech did extensive tests upon the let breathe flow meter and said it was good. as soon as I unplug it and rule the motor, the car runs severe and at 850ish. I can by yourself guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much control in the alternative of rpm though? I think it abandoned adjusts it roughly speaking 1k..
I don't have any check engine lights unless I unplug the MAF sensor. next the MAF is plugged in next the car will stall unless I put my foot upon the accelerator. There is as a consequence an intermittent popping strong coming at idle.
