Hello, I have repaired beyond 30000 vehicles in my career and I craving to ask you questions before I am not there in person to gather together facts, data, or to test your vehicle. I may question you to comport yourself testing in my stead. If breakdown is needed and you would rather not play-act testing, I can allow my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests on the air flow meter and said it was good. when I unplug it and control the motor, the car runs argumentative and at 850ish. I can lonesome guess that my further rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don't think the tps has that much control in the every other of rpm though? I think it unaccompanied adjusts it nearly 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you occurring to date upon all maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms occurring and is warmed up? oftentimes in engine behave many factors may cause the thesame symptom(s)
