￭ Idle rpm is too high after engine start

1. If you saw the "ISC air flow" in speedtuning is too big(normal is 20~40), you can follow below step to fix it:

    1.2 When engine key on, turn off and turn on 10 times in 15 seconds and key off the engine

2. If the "ISC air flow" in speedtuning is too small, maybe the intake air have leak air, please check the throttle body, intake manifold, you can use the throttle body cleaner to spay on all the intake area, if the idle rpm change suddenly, it is mean the intake leak air, please fix it.
