    hey all,
    Was hoping someone might have an idea on this one. Have a 2011 mack le600 front loader, no def system. Recently the trucks been running sluggish. Certain hills it normally pulls 35mph has been pulling 25 and sometimes down to 6mph. No engine codes (tech tools) however the lightning symbol is illuminated on the dash (electrical fault). We have no clue where to look so I figure a last ditch effort, maybe one of y'all have run into this issue? Running like it's under heavy load when it's empty. Forced regen a few times in the past and has helped temporarily. As of now just regened and no improvement. Any advice would be great
