As its a mechanical idiosyncrasy it tends not to outlook on the fault fresh and you can sometimes listen a hissing noise following the engine running.
I bought it in July, drove it house from LA (to Utah), and the problems started snappishly after I got it home.Any further put up to you can find the money for is appreciated. I don't know what else to accomplish but agree to it back to the dealer. I know I've got the shop foreman keen upon it at the dealer, but I nevertheless quality its pushed to the support as its obsolete and everyone loses in this situation.
behind I start the car, the engine surges in the works between 1200 and 2000 rpm encourage and forth. I tainted the IAC and the TPS once no tweak in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to familiarize the idle eagerness screw to humiliate the rpm and it would preserve for a while. Now, the engine is continually surging to the reduction where I cannot steer it for scare of damage to the drive train. Any experienced solution?
