s.e.s. light on off on

[DMAXED]

I made my first trip snowmobiling this year I was about two hours into the trip and the s.e.s. light comes on for about ten seconds shuts off ten minutes later the light came back on and off .it happend four times on the trip up and three times on the way home . I have been juiced since last july with no trouble 3.61c I put on a banks exhaust and a afe stage two cold air intake in november. the light seemed to come on when I was going up hills , I think it might be the mass air flow sensor the truck will into the shop to check for codes this week. has this happen to anyone else. any info would be helpful

thanks

Had same problem in late 2002. Long story short dealer could not find problem and said my Banks monster exhaust and break system was at fault, The boys at Banks found that the EGR valve had a small pin hole that was resposible for the SES reading. Hope this helps and save you some time.
