I may ask you to work scrutiny in my stead. If examination is needed and you would rather not affect testing, I can offer 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 suffering history. It currently has a master tech recognized idle freshen govern valve and tps installed. without disturbing anything, the last (used) ecu and my original, would control in the car without this symptom.
