2012 Sportsman 800 we have played with the throttle position switch and have the gap set correctly. When the machine is at idle and u short the switch out with a screwdriver nothing happens however if u run the RPM's up and short the switch with screwdriver it kills the machine like it should. The reason I ask is that sometimes the machine idles poorly and then will die could I have a broken wire, any idea how to diagnosis the problem?

Thats not the TPS on the handlebars, thats the ETC electronic throttle control, its designed to make it miss if throttle sticks, the Tps is under the seat and needs special tools to set it, thats probably where your problem is.
