This could be an airleak after the airflow meter, any ventilate 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 plus permit the engine to rev in the works like not desired causing argumentative running. As its a mechanical malfunction it tends not to approach on the fault light and you can sometimes hear a hissing noise following the engine running.
I'm 1500 too high.. or more. It's boggling to me how this difficulty has morphed into various idle problems and has everyone perplexed.. or as a result it seems. I've been dealing gone this before July.. makes me appreciate my 240z 10 era more.My dad owns an sc400 and its been truly fine to him.. I'm having a difficult become old not instinctive critical taking into consideration this purchase. I reach environment in the manner of its a fine car though. Motor sounds gorgeous and is super mild in the same way as dealing out right.
This could be a large vacuum leak ,with the MAF linked it is isolated measuring the ventilate that is getting taking into consideration the MAF, in view of that if the intake manifold is sucking in air 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. next carb cleaner spray spray in the place of the hissing afterward the engine executive and later you hear the engine stall or rev unconventional there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
