So new problems today, took my sled out from a heated garage that it was in overnight started up perfectly fine, drove up the road with it on a trailer about 30 miles. Got to the riding spot, went to start it, wouldn't start, wouldn't start, cranked and cranked and cranked. Tried the electric start and pull start equally. Finally after giving it some gas it sorta burbled, and then started, but would not idle unless I had my hand on the throttle, giving it a little bit of gas. After about 10-15 mins of that it was fine and seemed to be fine the rest of the day. Soooooo wtf? Its been fine until this morning, at least in the starting and idle regard so I don't think its the TPS issue. Last night I had it blow a spark plug out of the cylinder while riding, which I replaced with a new one ( just replaced both a couple days ago) So I guess I must not have had it tight enough? Thought it was plenty tight, never had that happen before. Any ideas? Would this leave a code for the dealer to see? I have warranty till I think 2019
