Hello, I have repaired higher than 30000 vehicles in my career and I compulsion to question you questions before I am not there in person to hoard facts, data, or to test your vehicle. I may question you to con psychiatry in my stead. If study is needed and you would rather not comport yourself 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 say you a little more just about the pain history. It currently has a master tech certified idle expose run valve and tps installed. without moving anything, the last (used) ecu and my original, would run 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 all maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms happening and is warmed up? oftentimes in engine conduct yourself many factors may cause the similar symptom(s)
