HI, The belly bumper lid has to arrive off as a couple of demean headlamp assembly bolts are located astern it. Here are directions please remember to rate relieve using the rating page as a result that I may get credit. Thanks
I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. next I unplug it and govern the motor, the car runs rasping and at 850ish. I can without help guess that my further rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of all this. I don't think the tps has that much direct in the interchange of rpm though? I think it only adjusts it around 1k..
bearing in mind I begin the car, the engine surges up in the middle of 1200 and 2000 rpm back and forth. I changed the IAC and the TPS past no amend in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to adapt the idle enthusiasm screw to belittle the rpm and it would keep for a while. Now, the engine is permanently surging to the narrowing where I cannot drive it for fright of broken to the drive train. Any experienced solution?
