Hello, I have repaired more than 30000 vehicles in my career and I craving to question you questions before I am not there in person to gather together facts, data, or to exam your vehicle. I may question you to appear in study in my stead. If laboratory analysis is needed and you would rather not conduct yourself testing, I can give my best advice, Fuel pressure?
I bought it in July, drove it home from LA (to Utah), and the problems started unexpectedly after I got it home.Any other urge on you can allow is appreciated. I don't know what else to reach but say you will it encourage to the dealer. I know I've got the shop foreman lively upon it at the dealer, but I still air its pushed to the help as its old-fashioned and everyone loses in this situation.
considering I start the car, the engine surges happening amongst 1200 and 2000 rpm help and forth. I tainted the IAC and the TPS when no change in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to adjust the idle speed screw to belittle the rpm and it would hold for a while. Now, the engine is all the time surging to the dwindling where I cannot drive it for buzzer of broken to the steer train. Any experienced solution?
