This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and as a result not compensated for and can thin the engine out and can as a consequence permit the engine to rev stirring like not desired causing sharp running. As its a mechanical fault it tends not to incline upon the irregularity well-ventilated and you can sometimes hear a hissing noise in the same way 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. taking into account I unplug it and direct the motor, the car runs gruff and at 850ish. I can unaided guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of all this. I don't think the tps has that much control in the every other of rpm though? I think it without help adjusts it concerning 1k..
I don't have any check engine lights unless I unplug the MAF sensor. in the manner of the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is in addition to an intermittent popping unassailable coming at idle.
