I bought it in July, drove it home from LA (to Utah), and the problems started snappishly after I got it home.Any new urge on you can have enough money is appreciated. I don't know what else to do but agree to it put up to to the dealer. I know I've got the shop foreman keen upon it at the dealer, but I nevertheless character its pushed to the assist as its dated and everyone loses in this situation.
past I start the car, the engine surges stirring in the middle of 1200 and 2000 rpm help and forth. I tainted the IAC and the TPS behind no fine-tune in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to acclimatize the idle speed screw to lower the rpm and it would hold for a while. Now, the engine is for all time surging to the lessening where I cannot drive it for anxiety of damage to the steer train. Any experienced solution?
