My big sweeper, 06 freightliner m2 w/cat c7/Allison 3500 has developed a very annoying problem that freightliner cant find, after the pto has been on for a bit (sweeping) the motor will start surging, as I know it the computer wants to give the motor 150 rpm when the pto is on, not specific to idle but any rpm up to governer limits, and this is what seems to be acting up. Does anyone have any insight on what the problem or fix could be?
