2003 Mack Mr truck E-7 engine. Problem with truck stumbling some. Inactive code keeps coming up no 3 eup. and data link.

Also replaced transfer pump and cam sensor. Wiring seems good. 4 volts going to every eup and pulse is the same on every eup. Haven't programmed rip but was told rarely that is a problem and I have swapped eup before never a problem. I have. Good software that trouble shoots coded and solutions. At a loss. Have own macks. 30 yrs. … read more
