Have a sportsman 700 efi. Recently the unit started missing really bad. it would clear up and then do it again. Now its doing it again and seems to only be firing on one cylinder due to the strong smell of unburned gas. Cleaned map sensor,and other electrical components but with no fix. I think i may have a plug wire problem. Any imput would be appreciated thanks

 

Check the plug wire on the right cylinder,pretty common for them to rub on the metal clip that holds the injector wire on.

 

yep , check both cap and the wire to replace.
