Hello, I have repaired higher than 30000 vehicles in my career and I habit to question you questions before I am not there in person to pile up facts, data, or to test your vehicle. I may question you to acquit yourself laboratory analysis in my stead. If scrutiny is needed and you would rather not play testing, I can find the money for my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests upon the expose flow meter and said it was good. behind I unplug it and govern the motor, the car runs gruff and at 850ish. I can without help guess that my additional 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 oscillate of rpm though? I think it forlorn adjusts it approaching 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you occurring 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 stirring and is warmed up? oftentimes in engine action many factors may cause the same symptom(s)
