Hello, I have repaired more than 30000 vehicles in my career and I habit to question you questions back I am not there in person to hoard facts, data, or to test your vehicle. I may ask you to put-on chemical analysis in my stead. If examination is needed and you would rather not feign 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 tiny more virtually the pain history. It currently has a master tech approved idle freshen direct valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would rule in the car without this symptom.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you going on 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 occurring and is warmed up? oftentimes in engine undertaking many factors may cause the thesame symptom(s)
