Hello, I have repaired more than 30000 vehicles in my career and I need to question you questions back I am not there in person to gather together facts, data, or to exam your vehicle. I may ask you to play-act psychotherapy in my stead. If breakdown is needed and you would rather not be active testing, I can come up with the money for my best advice, Fuel pressure?
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me say you a little more approximately the hardship history. It currently has a master tech ascribed idle expose manage valve and tps installed. without disturbing anything, the last (used) ecu and my original, would direct in the car without this symptom.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you up 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 taking place and is warmed up? oftentimes in engine accomplishment many factors may cause the thesame symptom(s)
