mcratchet1 Posted March 8 Share Posted March 8 (edited) Just had a question I have 07 mr688s cab over lately I’ll get no response to pedal for a split second while driving it always happens around 1300-1600 rpm’s it was maybe once a day now it’s most of the time. I check the batteries, connections, grounds, etc. awhile back I had no response to pedal at all so change the pedal sensor. It does not log any codes. I have checked EUP connections also. Any advice would be greatly appreciated Edited March 8 by mcratchet1 Quote Link to comment https://www.bigmacktrucks.com/topic/73943-throttle-unresponsive/ Share on other sites More sharing options...
Joey Mack Posted March 8 Share Posted March 8 Did you use Mack Software to do a pedal calibration? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73943-throttle-unresponsive/#findComment-547827 Share on other sites More sharing options...
