This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and in view of that not compensated for and can lean the engine out and can moreover permit the engine to rev occurring once not desired causing rude running. As its a mechanical anomaly it tends not to slope on the malformation spacious and you can sometimes hear 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. past I unplug it and run the motor, the car runs aggressive and at 850ish. I can only guess that my additional 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 run in the substitute of rpm though? I think it on your own adjusts it on 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you going on to date upon every maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms happening and is warmed up? oftentimes in engine feint many factors may cause the same symptom(s)
