So at what RPM is it misfiring? Are you just trying to rev it up in place or are you running down the trail when it miss-fires?
It sounds like your wiring harness is shorting into the frame of the sled. Look for wire chaffing and shorting in the nose of the sled by the ECU and around the steering post and handle bars. One of the wires shorting is probably the Grip Warmers, if you are getting the code and misfire at the same time.
The Grip Warmer wire is a Yellow/Red wire. Pay particular attention to it. It is not fused. So you need to take care of this ASAP to avoid damaging the ECU.

thank for the reply, i start with all the basic stuff , i had replaced all four coils last year, with aftermarket ones, kept the old ones, i check all the wiring like you said, could see any problems, test the wiring from the thumb warmer, it was good, i changed all the coils to the old ones , just to try and its fixed, it runs good and no more lights flashing, thanks goodday

During your inspection and testing you probably moved the wire from the place it was shorting. You may want to go back and try to find the spot on the wire and re-insulate it. Otherwise, the problem may reoccur, with more dire results.
Changing the coils, has nothing to do with getting an Grip Warmer Code. However, you may have had two problems. Did you test the coils to find the smoking gun? Are the replacements that you took out the right coils? We recently had a user that had the wrong coils in there causing the ECU to show an error code on the ignition system. Some of the newer coils show a higher resistance value and the ECUs pick up on this.
