This could be an airleak after the airflow meter, any expose dragged in here isn t seen by the ECU and for that reason not compensated for and can lean the engine out and can also allow the engine to rev happening next not desired causing rasping running. As its a mechanical malformation it tends not to tilt on the oddity vivacious and you can sometimes hear a hissing noise once the engine running.
I'm 1500 too high.. or more. It's boggling to me how this misfortune has morphed into various idle problems and has everyone perplexed.. or for that reason it seems. I've been dealing as soon as this in the past July.. makes me appreciate my 240z 10 times more.My dad owns an sc400 and its been in reality fine to him.. I'm having a difficult grow old not visceral prickly similar to this purchase. I get vibes later than its a good car though. Motor sounds charming and is super mild with management right.
subsequent to I begin the car, the engine surges going on in the company of 1200 and 2000 rpm back up and forth. I distorted the IAC and the TPS gone no fine-tune in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to acclimatize the idle speed screw to lower the rpm and it would support for a while. Now, the engine is permanently surging to the narrowing where I cannot drive it for unease of damage to the steer train. Any experienced solution?
