Its a 2011 pro rmk

First thought is TPS....since it seems so common. Bad or just not adjusted correctly.

my tps went bad, started little, just a bog a partial throttle, then got worse and worse until finally you couldnt hold it under 6000 rpms

The TPS was adjusted one week ago..
It runs like it should at idle and all the way up to 3/4 throttle.
How does the "throttle freeze protection" affect the sled if something is wrong there?

The TSS will think you have a stuck throttle if you have too much slack in the throttle cable. Adjust that out and you should be good2go! Other thing is it sounds pretty icy in your vid so could be the timing being pulled if your motor was getting hot.

Have FUN!

Hmmm... I would also say TPS. Even if it is adjusted properly you could have gotten moisture in it. If you get it dried out then pack some dielectric grease in it, it may help. Although I have never had a problem with a TPS so I wouldn't know for sure how it would react in such a situation. You could try changing your fuel filter as well.

check those fabric covers on your electrical connections..mine were full of water!!!!!.............causing the unused plugs to be in a puddle of water

Must be a 2011? My 11 had injectors that went out and acted that way.

Let us all know when you figure it out, my 2012 started doing this intermittently last week, but when I would let go of the flipper and resqueeze it would run fine.

Injectors.

Exact same symptoms as 2 of my buddies 11's. New injectors fixed both of them.

My 2012 is doin the same thing,Squeeze the throttle it would bog, let up and get on'er it would good. It only did this a couple of times. At the dealer right now.

It doesn't sound like it is the TPS this time, but just because it is adjusted correctly doesn't mean that it can't still be bad. I had one that would set good but the internal resistance was not correct and caused it to cut out mid throttle.

We had a fuel pump in ours go bad that caused weird bogs like that.

Now the sled runs better than ever, it was a very simple problem, Nr12 in this picture was broken. http://www.ronniesmailorder.com/fic...Snowmobiles&make=Polaris&year=2011&fveh=39734
And i also did clean up all parts to the VES system.

Yap, I had one that run the same way and it turned out to be a plugged VES system. Its best to remember the KISS method first.

My 2011 Assault 155" started doing the same thing today.
It's not as common as in your video. It's dying more randomly, when I'm giving full throttle. It's quite dangerous to do climbing with this problem...


What is the "TPS"?

Thanks!

Throttle Position Sensor "TPS" is located on the PTO side of your throttle boddies and has two little screws holding it on. I believe it's a three wire connector with a rubber booty on it.
