I did re-check them tho. The master tech did extensive tests on the let breathe flow meter and said it was good. following I unplug it and govern the motor, the car runs argumentative and at 850ish. I can on your own guess that my extra 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 control in the alternating of rpm though? I think it single-handedly adjusts it re 1k..

have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you in the works to date on every 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 play in many factors may cause the same symptom(s)
