Hello, I have repaired beyond 30000 vehicles in my career and I habit to question you questions since I am not there in person to hoard facts, data, or to test your vehicle. I may question you to be active chemical analysis in my stead. If psychiatry is needed and you would rather not show testing, I can provide my best advice, Fuel pressure?
I bought it in July, drove it home from LA (to Utah), and the problems started snappishly after I got it home.Any extra back up you can meet the expense of is appreciated. I don't know what else to realize but acknowledge it back up to the dealer. I know I've got the shop foreman working upon it at the dealer, but I still setting its pushed to the help as its dated and everyone loses in this situation.
similar to I begin the car, the engine surges happening together with 1200 and 2000 rpm help and forth. I misused the IAC and the TPS in imitation of no fine-tune in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to accustom yourself the idle quickness screw to humiliate the rpm and it would keep for a while. Now, the engine is every time surging to the reduction where I cannot steer it for radio alarm of damage to the steer train. Any experienced solution?
