SOURCE: engine on my 04 sportsman 400 wo'nt idle unlesss

there is an electronic position sensor in the throttle housing and if the throttle cable sticks even a little the sensor interrupts the flow of electricity and disables the engine to prevent loss of control so chase down your cable and lubricate it and make sure you have full range of movement

SOURCE: Stalling out

I am assuming that your unit has fuel injection. Sounds like you might have a clogged fuel injector. Recomended is Polaris fuel injector cleaner but I believe you can use fuel injector cleaner from a part store but make sure it is diluted according to the instructions. However, being that your unit is a 2009 model, I would think that any polaris dealer would cover this under warranty being less then 1 yr old. If they won't cover the repair, then try injector cleaner. Good luck and happy trails.

Engine won't idle /sometimes backfires

Check the MAF-MAP SENCER or it's a throttle position sencer is bad check both by replacing them and see if it works or the last result is idle control valve
