Hello, I have repaired greater than 30000 vehicles in my career and I need to question you questions since I am not there in person to pile up facts, data, or to exam your vehicle. I may ask you to perform laboratory analysis in my stead. If study is needed and you would rather not function testing, I can give 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. taking into account I unplug it and rule the motor, the car runs rude and at 850ish. I can unaided guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much control in the vary of rpm though? I think it on your own adjusts it around 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you up to date upon 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 do its stuff many factors may cause the same symptom(s)
