DC72 Posted 7 hours ago Share Posted 7 hours ago Looking for help! This unit runs as a yard truck with PTO for auger/blend system. Normally runs at 1100rpms while pto is engaged. Problem is it will intermittently stumble/hiccup while running on the high idle, sometimes once or twice other times repeatedly. I cannot run this down the road to a dealer to get it plugged in and no one will come here due to age and software needs, internet etc. Any thoughts on what could be causing this? I have already replaced accelerator pedal with solved the problem of occasionally not staying on high idle, originally thought they were the same problem but apparently not! Appreciate any help...Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/75521-2006-mack-cv-713-120l-ami-370-stumble-on-high-idle/ Share on other sites More sharing options...

DC72 Posted 2 hours ago Author Share Posted 2 hours ago just the lightning bolt, not check engine light Quote Link to comment https://www.bigmacktrucks.com/topic/75521-2006-mack-cv-713-120l-ami-370-stumble-on-high-idle/#findComment-575771 Share on other sites More sharing options...
steeler Posted 1 hour ago Share Posted 1 hour ago Yours doesn't have a check engine light, just the lightning bolt and red shut down light. You can get the lightning bolt to blink any active codes for you by turning cruise off, then hold down (I think it's down?) the set/decel switch until the light starts blinking a 2 digit number... 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75521-2006-mack-cv-713-120l-ami-370-stumble-on-high-idle/#findComment-575781 Share on other sites More sharing options...
