Riding yesterday at around 4000 feet elev in the rain, my 400 would load up and start missing every time a good load was put on the engine. Hills I normally go up in 3rd gear high range, I ended up having to gear down to 2nd or even 1st in low range to get over....the engine was running so poorly. On the flat everything was fine, but any little hill or mudhole and the engine would missfire like crazy and drop RPM. At the end of the day, I also used about 4 times more fuel than anyone else.

I'm going to take it to my dealer since its under warrantee, but I'd like to see if others have had similar problems and what was done to fix it.
