Hello, I have repaired over 30000 vehicles in my career and I dependence to ask you questions since I am not there in person to hoard facts, data, or to exam your vehicle. I may question you to pretend breakdown in my stead. If psychoanalysis is needed and you would rather not pretense testing, I can find the money for my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests on the ventilate flow meter and said it was good. past I unplug it and control the motor, the car runs rough and at 850ish. I can lonesome guess that my new 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 govern in the stand-in of rpm though? I think it solitary adjusts it around 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you up 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 happening and is warmed up? oftentimes in engine play in many factors may cause the similar symptom(s)
