I just got my new 2012 Rhino, went out in the hills for a ride. Everytime I coast down a hill with my foot off the gas it starts backfiring. Not continuosly, but about every 30 or 40 yards, pow like a rifle shot. Called the dealer and they seemed really puzzled. That worries heck out of me if they don't have a clew. So tomorrow I'll take it back to them. If anyone has any ideas that I can relay to the mechanic I would sure be thankful to you.
