2021 Skidoo turbo firing on 1 cylinder

[Sean Webb]

Was out for a weekend of sledding, running great, and on the day that we left it was -40c, checked coil, changed spark plugs, checked for spark out of the plug wires, and after many starts still doing the same thing, anyone else having these problems???

Plugs indexed properly?

 

[Sean Webb]

Yes, was still doing it on the factory plugs to

Only weird thing is when I pulled the plugs they looked normal, and it cant be the fuel cause the other cylinder is firing.

I would take to dealer rather than going through the unit and taking apart something that can cause any issues with warrantee. They note these on the unit history as well, if something if found later on and it goes back to that at least you have a case to get it covered if so. I'm sure your not going to miss it for upcoming Family day weekend, its going to be just as cold according to weather updates.

 

[Sean Webb]

yea im gonna take it to the dealer tomorrow, but thanks anyways for the help

Sounds a lot like fouled plugs. Problem being is that when I checked last week the spark plugs for the 21 turbo are on backorder everywhere. the 20.5 turbo uses the same plugs as the NA 850 so you could try those out. ILKR8Q7 NGK iridium.

spark plug wire...

woudn't be too concerned it will still have lots of power. as long as it looks good. fit 'n finish is really where it's at these days.

Generally they will not run on one cyl.

I know of two 2021 turbos with 1 faulty coil and they would die and not start.

Perhaps its like MSD Or what ever thats called, where they deactivate cylinders under low load and bring them back on seamlessly when power is required.

on a serious note, did you check resistance on the plug wires? As long as there a normal consistent number should be ok. Say 1k to 4500 ohms kinda thing. Not sure if it would matter as far a checking spark, but make sure wires aren’t chris crossed. I don’t know on an 850T, but the lower coil on my xm is the Pto side. Coil connectors are firm And properly clipped? I was watching a tether install recently and while they were monkeying around with that it inadvertently cause a coil clip to come undone.
