  1. Great, thanks for the help. And if i wanted to have the "step 12b" software put in i can only have that done through a dealer correct?? And what exactly doe the step 12b software do?
  2. It is a 2004, and i cleaned out all the sand and grim from under the pedal and lubricated all rollers and piviot points. I also found that the metal pedistal that the pedal rolls on had a grove in it causing the roller to hang up, so I ground down the grove and smoothed it out. Those things helped, but the pedal is still pretty sensitive, the slightest movement in the pedal makes a big jump in RPM's. Thanks in advanced for all help or suggestions
  3. We have a late model Mack CX613 Vision, andwe are having a problem with the fuel pedal sensitivity. It seems like the fuel pedal is "sticky" and when you are trying to give it low fuel it is very jumpy and hard to control fuel level. Is there a way to adjust the fuel pedal sensitivity??
