Hey just I have a fuel injected 2012 450r and I'm having a problem with it high idling and revving on its own I can seem to find the issue sometimes it's worse and sometimes it's fine. If anyone has any ideas any help is appreciated

Check for air leaks. If the idle is hanging or just staying high, you probably have an air leak somewhere...assuming it's not a mechanical hang in your cable or TB.

Pull the isc motor and turn the key. You should see the plunger pulse a few times.
