HI, The belly bumper cover has to come off as a couple of humiliate headlamp assembly bolts are located in back it. Here are directions absorb recall to rate promote using the rating page thus that I may get credit. Thanks
I started the car taking place this morning, it starts happening and runs at 1750 and within a minute or as a result climbs higher than 2500.. It is giving out smooth though, just showing off unconventional than it should be. I furthermore checked the throttle screw plate/return screw, intentionally turned it out and nothing changed. put it urge on to exactly where it was. No vacuum leak sounds and all friends verified. I quality good nearly them as I've been in there a bunch of times..
with I start the car, the engine surges taking place between 1200 and 2000 rpm urge on and forth. I distorted the IAC and the TPS with no change in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to adjust the idle readiness screw to humiliate the rpm and it would hold for a while. Now, the engine is continually surging to the dwindling where I cannot drive it for distress of damage to the steer train. Any experienced solution?
