Hello, I have repaired higher than 30000 vehicles in my career and I obsession to ask you questions before I am not there in person to accrue facts, data, or to exam your vehicle. I may ask you to put-on examination in my stead. If breakdown is needed and you would rather not behave testing, I can pay 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 practically the hardship history. It currently has a master tech certified idle ventilate direct valve and tps installed. without heartwarming 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 going on 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 taking place and is warmed up? oftentimes in engine operate many factors may cause the similar symptom(s)
