My 2012 Mack Granite Dump truck idles fine but when I put it in gear and start to shift if bogs down or when it is running and shifting good when I put a load on it looses power. Cleaned both fuel tanks put new filters and can't find problem any solutions please.
Idles but bogs when accelerating or carrying a load
