2007 Mack granite mp7. We are getting a dead pedal at times. It will pull fine and then you can be running 60 pedal Go dead and might not pick back up until 40.
When it starts doing this , even when it picks back up you can tell it’s not at full power. Then your liable to stop at stop sign take off and it never do it again all day.
This has been a reoccurring issue. We aren’t getting any fault codes (we think) we hope we are checking them right as the process is confusing.
Any help would be appreciated.
