Sorry but I kinda need a fast help. I am having family over for a ride through VT and I developed a problem.
I have a 2010 550 sportsman EFI and electric steering. It was riding great, stopped put it in Neutral, idled fine. put in gear and it started to load up and backfire, got it back in Neutral and it cleared up. put it in gear and it backfired and bucked.
so it runs ok in park and runs like dirt in gear. even if it is in gear and Idling it runs like dirt.
So I am thinking could it be the switch on the tranny? does this switch tell the computer to do something to the timing or injectors?
I am kinda desperate for help.
thank all.
