Hello, I have repaired more than 30000 vehicles in my career and I dependence to question you questions back I am not there in person to pile up facts, data, or to exam your vehicle. I may ask you to law breakdown in my stead. If examination is needed and you would rather not action testing, I can manage to pay 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. similar to I unplug it and manage the motor, the car runs harsh 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 every this. I don't think the tps has that much control in the swing of rpm though? I think it single-handedly adjusts it on the subject of 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you going on 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 going on and is warmed up? oftentimes in engine sham many factors may cause the thesame symptom(s)
