He tried my used ones.. and finally a rebuilt one. still had issues. encourage to the dealer.. this period he says, it needs a ECU.

I bought it in July, drove it house from LA (to Utah), and the problems started unexpectedly after I got it home.Any additional urge on you can come up with the money for is appreciated. I don’t know what else to pull off but recognize it put up to to the dealer. I know I’ve got the shop foreman energetic upon it at the dealer, but I still setting its pushed to the back up as its archaic and everyone loses in this situation.

bearing in mind I start the car, the engine surges stirring amongst 1200 and 2000 rpm back up and forth. I misused the IAC and the TPS in imitation of no regulate in symptoms. I have noticed that several Lexus SC’s have this same issue. Prior to this I would have to familiarize the idle swiftness screw to lower the rpm and it would sustain for a while. Now, the engine is each time surging to the narrowing where I cannot drive it for warning of damage to the drive train. Any experienced solution?
