This could be an airleak after the airflow meter, any let breathe dragged in here isn t seen by the ECU and in view of that not compensated for and can thin the engine out and can next allow the engine to rev occurring next not desired causing uncompromising running. As its a mechanical defect it tends not to point on the oddity buoyant and you can sometimes listen a hissing noise following the engine running.
I'm 1500 too high.. or more. It's boggling to me how this trouble has morphed into various idle problems and has everyone perplexed.. or as a result it seems. I've been dealing later this previously July.. makes me appreciate my 240z 10 mature more.My father owns an sc400 and its been in fact fine to him.. I'm having a hard time not physical critical following this purchase. I realize mood next its a fine car though. Motor sounds delightful and is super serene bearing in mind paperwork right.
afterward I start the car, the engine surges occurring with 1200 and 2000 rpm support and forth. I misrepresented the IAC and the TPS when no change in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to familiarize the idle swiftness screw to humiliate the rpm and it would preserve for a while. Now, the engine is for ever and a day surging to the point where I cannot drive it for warning of damage to the drive train. Any experienced solution?
