Hello, I have repaired higher than 30000 vehicles in my career and I need to question you questions in the past I am not there in person to collect facts, data, or to exam your vehicle. I may question you to produce a result examination in my stead. If examination is needed and you would rather not do something 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 unexpectedly after I got it home.Any supplementary urge on you can find the money for is appreciated. I don't know what else to reach but believe it incite to the dealer. I know I've got the shop foreman functioning on it at the dealer, but I nevertheless feel its pushed to the back as its obsolete and everyone loses in this situation.
as soon as I start the car, the engine surges taking place amongst 1200 and 2000 rpm incite and forth. I distorted the IAC and the TPS gone no amend in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to get used to the idle readiness screw to demean the rpm and it would sustain for a while. Now, the engine is at all times surging to the point where I cannot drive it for alarm bell of damage to the drive train. Any experienced solution?
