My 2014 T four seater will not idle but will run. It is sluggish. I took it for a short ride and the exhaust system caught the axle boots, cargo and rear console on fire. I noticed the fire underneath after I started to turn around and got off of the side by side and realized there were flames underneath. I have already ordered two axles, cargo and cover rr console. How can I repair the idling problem and has anyone else experienced this situation? I checked the the spark arrestor which was clean and beat on the muffler with a rubber mallet and nothing came out. I don’t know why the exhaust system became so hot either. Help!
