I need some help as the dealers can’t figure out what’s wrong with the sled. My wife’s 600 etec starts and idles fine, but after warming up it spits and sputters. You can throttle through it and it will run fine after about 30 seconds. It won’t do this on a stand only with a load on the sled. This only happens when you first start it in the morning. The motor is warmed up properly before trying to move. Any help would be appreciated.
2016 600 Etec misfire after initial warmup

I know you said the dealer looked at it, so they should be intelligent enough to check out your plugs...but when I was having a similar issue, the dealer said the etec plugs will have no issues for thousands of miles. Sure enough, I pulled the plugs, cleaned them up, and it ran good again. I think it was from a couple of fogging cycles with no actual heat cycles or running. Another thing to possibly have checked is your stator and coils. As electrical parts get warm, they can sometimes work differently than in the cold when they're going out. Try simple things first like the plugs and some additive, but my guess is your dealer would have done these things already. What have they tried to do?
Sled still has the same problem with no results changed plugs, and the dealer checked electrical parts and stated everything was working properly. I have tried warming the sled up to almost overheating along with everything below that, and it will still misfire and hesitate for about 30 seconds and then clears up and runs fine.
Did you get it running fine again?
Mine 600 etec seems to have the exact same problem.
New filter, plugs, temp sensor, checked the exhaust ports etc.
