I have a 2007 sportscoach with a C7 Cat motor and the last 2 days I have been having the check engine light come on for about 2 or 3 minutes then it goes off and does not come back on. Any Ideas?
"kg1d dx".....Did this occur under acceleration or while cruising on flat ground. Often the lights are triggered by clogged fuel filters and will turn the light on under acceleration. Low coolant could also turn the light on. If your filters are old, it might be worth it to change them out before buying any tools or taking it to a shop. Either way, the fuel filters should be changed if they're old.
