2004 sportsman 600 rough idle in cold weather
My 2004 sportsman 600 will barely idle in cold weather (below 0 celsius).If I pull the choke it will idle, but it is still a rough idle. I can still drive it but when I let off the throttle it wants too stall almost, & backfires. Sometimes I can shut it off for a couple of minuites and it will be fine. Sometimes when I first start it up & let it warm up it will run fine for a while then start to run rough and barely idle.
