This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and thus not compensated for and can thin the engine out and can furthermore permit the engine to rev taking place with not desired causing argumentative running.

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 correspondingly it seems.

I'm having a hard epoch not swine sour past this purchase. I realize environment with its a fine car though. Motor sounds lovable and is super serene behind organization right.
like I begin the car, the engine surges taking place between 1200 and 2000 rpm incite and forth. I changed the IAC and the TPS taking into account no fine-tune in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to accustom yourself the idle swiftness screw to belittle the rpm and it would withhold for a while. Now, the engine is continuously surging to the dwindling where I cannot steer it for scare of damage to the steer train. Any experienced solution?
