Check engine light coming on, with high idle?

[huntfish64]

Hey guys, I have 2015 600 RMK. At random times my check engine light comes on and it will idle at around 3500. The light comes on then goes away. I mess with the throttle and it will go back down to 1900ish. Last time it happened the sled died. And would not start until I held the throttle down and it was fine after it started. Trying to diagnose, need some help.


Thanks

Also.....the light flashes so fast, by the time it's on it goes away so I have no time to see if a code comes up with it.

next time this happens, don't turn engine off. Apply park brake and toggle through the display and the ERR code will show on the display. Once engine is shut off, the codes are stored in the background and need a tool to find them.
