Third this above. Or a reed petal broke off.

What was your previous problem? Mine doesn't come down from 2500 ever.

I am the one who started 2500 RPM idle post this summer, so this is my previous problem
Did you upgrade to the "Updated Yellow Injectors"?
Polaris had a run of 2011 "updated" injectors that are actually 2012 injectors with the 2011 part #'s on them. I encountered this recently when I was working on a rush, I upgraded to the "new" injectors and had the ECU reprogrammed, the sled never stopped idling under 2500 RPM. Tried everything, swapped electronics, ecu's, TPS, Tmap, reset TPS, I was going CRAZY trying to figure it out and was speaking with a Polaris tech rep going over a list of potential issues. I paused and said the only thing that was weird was the old injectors had 3 sealing 0-rings and the new injectors had 2 o-rings. He sent me a picture and when I verified I had removed 11 injectors and that the updated injectors were in fact mis packaged 12 injectors. Got new 11 injectors, and issue was instantly fixed.
Hey guys,
Just a little update. I finally had a chance to go wrenchin on my Pro.
First I synced the throttlebodies. I had a voltage of .704 when I did that. I then adjusted the tps to a voltage of .697-.698 it flashed back and forth... Then I adjusted the idle screw until I was at .922. I put everything back together and started it up. It idled at 2300-2500 rpm while warming up. Then at about 87F it idled down to 1700-2000rpm. I spun the track and she idled down to 2100, then after a couple seconds 1700-2000rpm. I'm going to give her a little run tomorrow, and check the plugs as well... just to be sure nothing else is going on. but all in all I think the problem is resolved!!
I owe a big thanks to you guys! and also I tossed my cheap multimeter and got a loan of a fluke! thanks guys!

That's why Polaris wants the dealers using DW, to take away the variables between meter quality.

this might be my case too, because I have 2013 engine on 2012 sled. Engine was blown, and changed under warranty. Looks like dealer left 2012 injectors on 2013 engine.
Hey,
False alarm..
I just went out and tie wrapped all the wiring back together and on to the frame and started it up.... she did not come down from 2500rpm at all.. Took her for a ride.. still 2500rpm. Not sure what is going on.

Ok something weird... if I press the reverse button the idle will go down to 1800, put it back in forward it will idle 1800... press the throttle and it doesn't come down from 2500.
Does anyone have any suggestions? I'm done...
Already tried that. Same thing.
Did you check for air leaks? Cracked throttle body boots or bad crank seals will create a lean condition and raise the idle.
The weirdest thing happened, I hooked up the stock computer and it idled fine. I hooked the PC5 back up and it's been idling 1700-2000rpm ever since. I still find it weird though. I set the parameters as low as possible. .697 for baseline. And .922 for idle. I'm just hoping I don't see the detonation light anymore.
