Hello, I have repaired higher than 30000 vehicles in my career and I craving to question you questions in the past I am not there in person to gather facts, data, or to exam your vehicle. I may question you to doing psychoanalysis in my stead. If study is needed and you would rather not behave testing, I can meet the expense of my best advice, Fuel pressure?
I bought it in July, drove it home from LA (to Utah), and the problems started suddenly after I got it home.Any extra incite you can manage to pay for is appreciated. I don't know what else to pull off but resign yourself to it back up to the dealer. I know I've got the shop foreman lively on it at the dealer, but I yet feel its pushed to the back up as its obsolescent and everyone loses in this situation.
when I start the car, the engine surges up amid 1200 and 2000 rpm urge on and forth. I misused the IAC and the TPS considering no alter 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 demean the rpm and it would maintain for a while. Now, the engine is continually surging to the point where I cannot drive it for terror of damage to the drive train. Any experienced solution?
