HI, The front bumper cover has to come off as a couple of subjugate headlamp assembly bolts are located in back it. Here are directions keep busy remember to rate relieve using the rating page hence that I may get credit. Thanks
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 suffering history. It currently has a master tech endorsed idle air rule valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would govern in the car without this symptom.
subsequently I start the car, the engine surges going on amongst 1200 and 2000 rpm support and forth. I misrepresented the IAC and the TPS similar to no correct in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to adapt the idle readiness screw to demean the rpm and it would maintain for a while. Now, the engine is all the time surging to the dwindling where I cannot steer it for fear of broken to the steer train. Any experienced solution?
