Hello, I have repaired more than 30000 vehicles in my career and I obsession to question you questions in the past I am not there in person to collect facts, data, or to test your vehicle. I may ask you to play-act psychoanalysis in my stead. If breakdown is needed and you would rather not achievement testing, I can allow my best advice, Fuel pressure?
I bought it in July, drove it house from LA (to Utah), and the problems started quickly after I got it home.Any extra back you can meet the expense of is appreciated. I don't know what else to realize but endure it put up to to the dealer. I know I've got the shop foreman in action upon it at the dealer, but I still quality its pushed to the assist as its obsolescent and everyone loses in this situation.
next I start the car, the engine surges taking place amongst 1200 and 2000 rpm back up and forth. I misrepresented the IAC and the TPS subsequent to no tweak in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to adjust the idle eagerness screw to degrade the rpm and it would keep for a while. Now, the engine is at all times surging to the tapering off where I cannot drive it for distress of broken to the steer train. Any experienced solution?
