Hello, I have repaired beyond 30000 vehicles in my career and I habit to question you questions previously I am not there in person to assemble facts, data, or to test your vehicle. I may ask you to conduct yourself chemical analysis in my stead. If study is needed and you would rather not be 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 little more just about the misery history. It currently has a master tech official idle freshen run valve and tps installed. without disturbing anything, the last (used) ecu and my original, would govern in the car without this symptom.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you stirring to date upon 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 con many factors may cause the same symptom(s)
