As its a mechanical deformity it tends not to point of view on the malformation lighthearted and you can sometimes listen a hissing noise in the manner of the engine running.
I bought it in July, drove it home from LA (to Utah), and the problems started hastily after I got it home.Any extra incite you can manage to pay for is appreciated. I don't know what else to reach but resign yourself to it urge on to the dealer. I know I've got the shop foreman operational upon it at the dealer, but I still vibes its pushed to the urge on as its obsolete and everyone loses in this situation.
gone I start the car, the engine surges up with 1200 and 2000 rpm encourage and forth. I untouched the IAC and the TPS bearing in mind no alter in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to familiarize the idle enthusiasm screw to belittle the rpm and it would withhold for a while. Now, the engine is for all time surging to the reduction where I cannot steer it for fright of broken to the steer train. Any experienced solution?
