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 approximately the suffering history. It currently has a master tech endorsed idle expose manage valve and tps installed. without disturbing anything, the last (used) ecu and my original, would govern in the car without this symptom.
considering I begin the car, the engine surges in the works amongst 1200 and 2000 rpm back up and forth. I changed the IAC and the TPS in the manner of no modify in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to become accustomed the idle promptness screw to demean the rpm and it would hold for a while. Now, the engine is for all time surging to the reduction where I cannot steer it for buzzer of damage to the drive train. Any experienced solution?
