Hello, I have repaired over 30000 vehicles in my career and I need to ask you questions before I am not there in person to store up facts, data, or to exam your vehicle. I may ask you to pretense psychotherapy in my stead. If investigation is needed and you would rather not operate testing, I can manage to pay for my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. behind I unplug it and run the motor, the car runs rude and at 850ish. I can single-handedly guess that my further rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of all this. I don't think the tps has that much govern in the rotate of rpm though? I think it only adjusts it re 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you happening 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 fake many factors may cause the thesame symptom(s)
