2015 Pro high idle, will die at idle, engine light on......

I have a 2015 Pro RMK and had no issues first ride out except for a plug wire that came loose. I reattached it quickly and had no issues rest of day. Yesterday, ran fine till midday and noticed sled idled at 3400 rpms, engine would want to die if I didn't feather throttle every couple seconds. Engine light would flash every once in a while. I didn't check to see what codes were showing up. Looking for any info or if anyone else has had this issue. Sled has around 100 miles and only add on's are pro armor tether and can. TIA

thank you for the replies. It ended up being the the throttle had no freeplay and had to loosen cable up quite a bit. Unusual being a rather new low mile sled. Mechanic also indicated bar bag that came with sled might have been restricting or messing with cable.......
