Hello, I have repaired over 30000 vehicles in my career and I need to question you questions previously I am not there in person to assemble facts, data, or to test your vehicle. I may question you to piece of legislation breakdown in my stead. If chemical analysis is needed and you would rather not pretense testing, I can offer my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests on the air flow meter and said it was good. following I unplug it and govern the motor, the car runs scratchy and at 850ish. I can only guess that my supplementary 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 swing of rpm though? I think it and no-one else adjusts it approximately 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you happening to date on 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 perform many factors may cause the thesame symptom(s)
