Hello, I have repaired higher than 30000 vehicles in my career and I habit to ask you questions since I am not there in person to accrue facts, data, or to exam your vehicle. I may ask you to show testing in my stead. If breakdown is needed and you would rather not perform testing, I can find 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 back you can meet the expense of is appreciated. I don't know what else to get but tolerate it support to the dealer. I know I've got the shop foreman operating on it at the dealer, but I still mood its pushed to the back up as its pass and everyone loses in this situation.
in the manner of I start the car, the engine surges happening with 1200 and 2000 rpm assist and forth. I tainted the IAC and the TPS bearing in mind no bend in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to adjust the idle quickness screw to degrade the rpm and it would preserve for a while. Now, the engine is at all times surging to the point where I cannot drive it for alarm bell of broken to the drive train. Any experienced solution?
