2009 International school bus with Maxxforce 7, low power, special up hill, almost stop at hill, sometime PRM went up to 2500, but speed still low, any idea? Thanks
Sounds pretty common lol.....Look up your tailpipe and see if you can see any honeycomb. We've had 3 this year that blew cat's apart and caused excessive backpressure.
Maxxforce 7 no power
