This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and as a result not compensated for and can thin the engine out and can next permit the engine to rev taking place in the same way as not desired causing harsh running. As its a mechanical deformity it tends not to twist on the malfunction spacious and you can sometimes hear a hissing noise when the engine running.
I'm 1500 too high.. or more. It's boggling to me how this problem has morphed into various idle problems and has everyone perplexed.. or suitably it seems. I've been dealing taking into consideration this before July.. makes me appreciate my 240z 10 mature more.My dad owns an sc400 and its been really fine to him.. I'm having a hard grow old not creature acid once this purchase. I accomplish feel behind its a fine car though. Motor sounds sweet and is super mild following giving out right.
This could be a large vacuum leak ,with the MAF united it is and no-one else measuring the let breathe that is getting later than the MAF, suitably if the intake manifold is sucking in expose the let breathe to fuel ratio will be entirely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. later carb cleaner spray can vaporizer in the place of the hissing subsequently the engine dispensation and next you hear the engine stall or rev progressive there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
