Hello, I have repaired higher than 30000 vehicles in my career and I craving to ask you questions past I am not there in person to build up facts, data, or to test your vehicle. I may ask you to pretend breakdown in my stead. If examination is needed and you would rather not show testing, I can meet the expense of 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. in the same way as I unplug it and direct the motor, the car runs uncompromising and at 850ish. I can and no-one else guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of all this. I don't think the tps has that much manage in the exchange of rpm though? I think it deserted adjusts it going on for 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 stirring and is warmed up? oftentimes in engine affect many factors may cause the same symptom(s)
