We've taken the Polaris Ranger in 5 times and their computer doesn't ever show anything wrong, also it doesn't miss for them as well. I drove the ATV around for 40 minutes for them and it didn't act up. The warranty is now JUST expired, so if my son & I could figure this out, maybe we can still make them fix the problem. The ATV sputters, acts like it wants to stall out. Any suggestions would be appreciated.

 

does it stall out and not want to run? whatis the condtions your riding in,wet swampy. dry? does it act like the override isnt being pushed in(dont know how it works on the ranger) when it acts up? did you get any water in the gas? just a few ideas.

 

Could possibly be intermittent short at t-map sensor wires. Located behind throttle body on air tube to air box. Bad location,goes under seat frame and zip tied into harness. Have had several that just a single wire would short causing rough idle,backfiring.

 

I just got back from feeding my animals and picking a little corn. On the way the ranger ran great, half way there it started doing the same thing. All the way back it ran terrible. I just parked it. We've drained the fuel tank in the past, and am really careful putting in gas. Problem isn't in wet areas, as we have all dry trails on the farm here. I think the polaris dealer replaced the wiring harness, will check though. Thank you!
