Hello, I have repaired beyond 30000 vehicles in my career and I compulsion to question you questions back I am not there in person to accumulate facts, data, or to test your vehicle. I may question you to con breakdown in my stead. If investigation is needed and you would rather not appear in testing, I can have the funds 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 tiny more about the suffering history. It currently has a master tech approved idle ventilate direct valve and tps installed. without moving anything, the last (used) ecu and my original, would control in the car without this symptom.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you happening 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 decree many factors may cause the thesame symptom(s)
