This could be an airleak after the airflow meter, any expose dragged in here isn t seen by the ECU and for that reason not compensated for and can thin the engine out and can along with permit the engine to rev occurring subsequent to not desired causing unfriendly running. As its a mechanical idiosyncrasy it tends not to point of view on the anomaly well-ventilated and you can sometimes listen a hissing noise considering the engine running.
I did re-check them tho. The master tech did extensive tests on the let breathe flow meter and said it was good. with I unplug it and run the motor, the car runs rude and at 850ish. I can unaccompanied guess that my other rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of every this. I don't think the tps has that much direct in the rotate of rpm though? I think it by yourself adjusts it around 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you taking place to date upon all maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms going on and is warmed up? oftentimes in engine conduct yourself many factors may cause the similar symptom(s)
