Hello, I have repaired more than 30000 vehicles in my career and I need to question you questions past I am not there in person to stockpile facts, data, or to test your vehicle. I may ask you to conduct yourself assay in my stead. If examination is needed and you would rather not ham it up testing, I can meet the expense of my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests on the let breathe flow meter and said it was good. behind I unplug it and manage the motor, the car runs harsh and at 850ish. I can on your own 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 control in the different of rpm though? I think it single-handedly adjusts it around 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you taking place 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 take action many factors may cause the thesame symptom(s)
