my 03 800X has just under 2000 miles and yesterday ate some plugs! trying to get it running was a chore. about -15c and it popped and bogged and fouled plugs. never did this before, what could it be? its also getting harder on fuel. I have the 2 yr engine warranty so should I take it in? it always seems rich too!

I would take that in right away freakshow,especially if you have the 2 yr warrenty
