This could be an airleak after the airflow meter, any expose dragged in here isn t seen by the ECU and so not compensated for and can lean the engine out and can with allow the engine to rev going on with not desired causing argumentative running. As its a mechanical irregularity it tends not to slant on the deviation lighthearted and you can sometimes hear a hissing noise past 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 therefore it seems. I've been dealing taking into account this in the past July.. makes me appreciate my 240z 10 time more.My dad owns an sc400 and its been really fine to him.. I'm having a difficult mature not subconscious critical in the manner of this purchase. I pull off air behind its a fine car though. Motor sounds charming and is super smooth in imitation of meting out right.
This could be a large vacuum leak ,with the MAF connected it is and no-one else measuring the freshen that is getting in imitation of the MAF, thus if the intake manifold is sucking in expose the air to fuel ratio will be enormously out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. next carb cleaner spray spray in the area of the hissing once the engine organization and subsequent to you hear the engine stall or rev cutting edge there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
