Did it throw any codes?
It may just be a coincidence that the low idle showed up after the overheat but things to check:
-anti freeze at a normal level?
-any anti freeze in oil? this usually shows up with decreasing antifreeze level and increasing oil quantity
Most common things to check:
-needs new plugs...change them
-plugged or dirty air filter
-vacuum line off
-boost tube split or leaking or clamp loose
-cracked or loose pipe from exhaust manifold to turbo

Hopefully just something simple....could just be really poor fuel as well.

My heat exchangers iced up a couple seasons ago. Same thing, lite came on, etc. I honestly thought something bad happened. Ran funny, like yours. Checked compression, new plugs. The next time I went to ride it, it ran flawless.
Can't explain, other than, I know what you're going through.

So changed out coolant, swapped out plugs, washed air filter and reset ecu, running back to normal. Thanks for all the advice.

Just a word of caution if you have drained and filled coolant these sleds are very difficult to bleed the cooling system to ensure there is no air in the system. Use the search function to get info on effective techniques.

Short answer for "no need to bleed". Get something like this: It vacuums out the air and sucks new coolant into the system.Great!
