HI, The stomach bumper cover has to come off as a couple of humiliate headlamp assembly bolts are located astern it. Here are directions keep amused remember to rate further using the rating page as a result that I may receive credit. Thanks
I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. following I unplug it and rule the motor, the car runs gruff and at 850ish. I can and no-one else guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of every this. I don't think the tps has that much run in the alternative of rpm though? I think it lonesome adjusts it on 1k..
later I begin the car, the engine surges up together with 1200 and 2000 rpm help and forth. I changed the IAC and the TPS gone no fiddle with in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to familiarize the idle speed screw to humiliate the rpm and it would maintain for a while. Now, the engine is continually surging to the lessening where I cannot drive it for fright of damage to the drive train. Any experienced solution?
