dallasw Report post Posted May 23, 2014 I have a 2011 Allegro Bus with a 450 HP Cummins engine. I had no prior issues but when I started it today the check engine/stop engine lights came on & stayed on. Tried to recycle several times with the same issue each time. Any suggestions before I call a tow truck to haul to closest Cummins dealer? Share this post Link to post Share on other sites
