Hello, I have repaired greater than 30000 vehicles in my career and I dependence to question you questions past I am not there in person to accumulate facts, data, or to exam your vehicle. I may question you to exploit assay in my stead. If laboratory analysis is needed and you would rather not bill testing, I can come up with the money for my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. subsequently I unplug it and rule the motor, the car runs severe and at 850ish. I can and no-one else guess that my supplementary rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of all this. I don't think the tps has that much direct in the substitute of rpm though? I think it single-handedly adjusts it all but 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you happening 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 up and is warmed up? oftentimes in engine measure many factors may cause the same symptom(s)
