Hello, I have repaired higher than 30000 vehicles in my career and I obsession to ask you questions in the past I am not there in person to pile up facts, data, or to test your vehicle. I may ask you to accomplishment examination in my stead. If examination is needed and you would rather not affect testing, I can find the money for my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. taking into consideration I unplug it and rule the motor, the car runs harsh and at 850ish. I can lonesome guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of all this. I don't think the tps has that much govern in the oscillate of rpm though? I think it abandoned adjusts it a propos 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you taking place 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 in the works and is warmed up? oftentimes in engine take effect many factors may cause the thesame symptom(s)
