Hello, I have repaired higher than 30000 vehicles in my career and I craving to question you questions past I am not there in person to gather together facts, data, or to test your vehicle. I may ask you to perform scrutiny in my stead. If examination is needed and you would rather not decree testing, I can meet the expense of 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 tell you a tiny more nearly the pain history. It currently has a master tech certified idle let breathe govern valve and tps installed. without disturbing anything, the last (used) ecu and my original, would manage 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 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 perform many factors may cause the thesame symptom(s)
