I'm 1500 too high.. or more. It's boggling to me how this burden has morphed into various idle problems and has everyone perplexed.. or for that reason it seems.

I'm having a hard time not inborn critical bearing in mind this purchase. I do character bearing in mind its a fine car though. Motor sounds delightful and is super mild like giving out right.
past I start the car, the engine surges stirring along with 1200 and 2000 rpm urge on and forth. I misused the IAC and the TPS later than no bend in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to familiarize the idle speed screw to lower the rpm and it would maintain for a while. Now, the engine is continually surging to the point where I cannot steer it for terrify of damage to the drive train. Any experienced solution?
