850 etec won't idle popping and backfiring at low rpm

[MK4TDI]

Is there a video or a procedure for that I have never had to change a plug on a etec.

Is there a indicator on the block so you know which way to point the electrode gap?

Are cat and polaris the same?

I use a felt marker to mark the plug, and mark it on the opposite side of the electrode so one can see it when you install it.

Stupid question but the throttle flipper has free play?? It's not all iced up?
had to help some young lads on frisby with an iced up throttle on the weekend.

Must have tool for all you Doo owners, makes pulling plugs a little easier. Still cancels out all you sausage fingers.

Hard to start idles at 850-900 rpm no p codes only starts and runs with throttle at 1/4 pressed pops and back fires at low rpm any ideas??

Your buddy ever figure out what was wrong with his sled?

 

[turboetech]

Sorry guys he has been a lazy f€%# and his sleds still sittin in my trailer but tells me he is picking up on Monday and headin to Martin in Edmonton as soon as I hear I will post his problem

 

[turboetech]

Did u change spark plugs?? It's a pain but if was my sled that's what I would do first but he won't because it's on warrenty...... lmfao

Well boys the 850 is at the hospital with a f?#% mag cylinder and piston.... something about ring loosened off and turned and scored cylinder maybe brp should use that Polaris glue to keep this from happening.... 1000kms on a 2017 850 165 totally stock.... noticed his rear shock in skid sacked out from new and he mentioned it while back for the first time for warrenty and apparently shocks are not covered... nice thanks brp...

Pretty sad, same thing happened to mine, I think this motor is becomeing a nightmare for doo, just heard about another in sparwood area, Linderman said he’s heard six last week all stuck with ring sticking exhaust port, said he thinks this is what Poo went threw a few years back, also could be the same as when they put boost to it, it allowed posting to stay centered better, and no more problems..

might be a sled to keep only only as long as warrenty last

 

[turboetech]

Martin in Edmonton had piston and jug in stock 2 day turnaround..... Buddy is smiling again

Good to here, some dealers are quick, than there is others that take two weeks before they look at the dam thing...

talked with anguy todaynthat has been down since the 02, riding a cat demo, said on service alone he is dealing next year..
