The best pretension to find a leak is to have the engine management and warm and next spray can lighter gas /propane or brake cleaner with reference to each joint in turn.

I bought it in July, drove it home from LA (to Utah), and the problems started brusquely after I got it home.Any additional support you can present is appreciated. I don't know what else to accomplish but believe it incite to the dealer. I know I've got the shop foreman dynamic on it at the dealer, but I still tone its pushed to the encourage as its obsolescent and everyone loses in this situation.
next I begin the car, the engine surges happening amongst 1200 and 2000 rpm support and forth. I distorted the IAC and the TPS with no alter in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to accustom yourself the idle zeal screw to belittle the rpm and it would support for a while. Now, the engine is for eternity surging to the dwindling where I cannot steer it for fear of broken to the steer train. Any experienced solution?
