2012 high idol and cuts out.

[TraceyAZ]

Hello, I've developed a small issue with one of my sleds. 2012 standard rmk 800. It has ran great for the last couple of years. This season I have a small issue that I need to fix. After it warms up it wants to idol up to high, 3k plus rpm, almost wants to engage the clutch. It also will not let it go into reverse when the idol is that high however I think that is by design. I have to shut it off, restart then put it in reverse quickly and repeat for taking it back out of reverse. It also will cut out on me for just a second when I go from a dead stop to full throttle. It clears and comes right back and will run at 65 mph at 8k rpm with no issue after that.
I would take it to a dealership but Im about 5 plus hours away from any that could help me. Im a good mechanic in general and have no issues with repairs once I know where Im going. I just don't want to throw parts at it guessing.
Any help from those who know would be great!
Thank you.

check and see if the throttle cable is to tight .if it isn't to tight . check for vacuum leaks

I’ve ruled out the throttle cable, all looks good there.
How do I check for vacuum leaks? And where?
I will say both these problems started at the same time.

you have to make sure the throttle plates are closed so pull the air box. spray starter fluid or use plain water in a spray bottle . spray around the crank seals and intake boots , but i really feel the throttle plate has a issue

Start with the above items, then also TPS adjustment or possibly reeds.
