Hello. I have a polaris sportsman 500 EFI x2 2007. The Atv dies when Idle, the machine is working at 1120-1180 and suddenly dies and backfire. the rpm are not stable. when the rpms are at 3000 rps suddenly goes to 2000 and then die. while driving is not smooth. at the begining i had this problem only when the machine was warm. approx after 30 minutes of use. now i have the problem all the time.
the check engine flashes and disappears.
i already visited a garage and they havent found something. they have cleaned the EFI system but again i have the same problem.
