Hello, I have repaired beyond 30000 vehicles in my career and I need to question you questions since I am not there in person to gather facts, data, or to test your vehicle. I may question you to perform study in my stead. If examination is needed and you would rather not function testing, I can come up with the money for 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 put up to you can manage to pay for is appreciated. I don't know what else to attain but believe it urge on to the dealer. I know I've got the shop foreman involved on it at the dealer, but I nevertheless environment its pushed to the back as its antiquated and everyone loses in this situation.
subsequently I start the car, the engine surges going on amongst 1200 and 2000 rpm assist and forth. I misrepresented the IAC and the TPS later than no tweak in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to adjust the idle enthusiasm screw to degrade the rpm and it would retain for a while. Now, the engine is until the end of time surging to the tapering off where I cannot drive it for panic of damage to the steer train. Any experienced solution?
