my 2011pro with s/turbo stopped idleing, reverse stopped working, and then proceded to run extreamly rich!! (un-rideable). turns out my tps (throttle position sensor) packed it in. my dealer will not warranty anything on my sled because of the turbo. so i tryed to order one and it turns out, almost every dealer in alberta and british columbia and spokane are sold out of these tps sensors. there is a back order and an updated version apparently. i did end up finding a store that had one in stock. just wondering how many other guys have had this issue, and why this is happening?
