HI, The tummy bumper lid has to arrive off as a couple of belittle headlamp assembly bolts are located astern it. Here are directions make smile remember to rate utility using the rating page as a result that I may get credit. Thanks
I started the car going on this morning, it starts happening and runs at 1750 and within a minute or thus climbs more than 2500.. It is supervision smooth though, just artifice highly developed than it should be. I with checked the throttle screw plate/return screw, deliberately turned it out and nothing changed. put it help to exactly where it was. No vacuum leak sounds and all links verified. I setting good not quite them as I've been in there a bunch of times..
gone I begin the car, the engine surges stirring between 1200 and 2000 rpm incite and forth. I untouched the IAC and the TPS when no fine-tune in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to adjust the idle rapidity screw to belittle the rpm and it would preserve for a while. Now, the engine is continually surging to the tapering off where I cannot drive it for fear of damage to the drive train. Any experienced solution?
