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 burden history. It currently has a master tech credited idle freshen manage valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would govern in the car without this symptom.
following I begin the car, the engine surges stirring surrounded by 1200 and 2000 rpm back up and forth. I changed the IAC and the TPS once no fiddle with in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to familiarize the idle enthusiasm screw to belittle the rpm and it would maintain for a while. Now, the engine is constantly surging to the point where I cannot drive it for fright of broken to the steer train. Any experienced solution?
