Hey guys. I have a 2009 Polaris sportsman 500 efi ho
I just did a full tune up on it not long ago
I went to ride it today and it idles fine and runs ok until you punch the throttle the check engine light comes on or if it gets to 4500+ Rpms it dose the. Same thing.
Any help would be greatly helpful
