Hey guys, I’m looking at buying a nice 2016 turbo RZR but once it’s warmed up it starts to misfire and backfire. It never overheats and only backfires once it’s warmed up. Any ideas what it might be? Could it be an internal engine issue like a burnt valve or a crack in the cylinder or valve seat that opens up when it gets hot? It’s not burning any coolant that I Can tell. Or is it something simple like a bad coil pack that fails once it’s warmed up? Thanks.
