My friend has a 2013 2500, saying it won’t pass an old lady with a walker while towing his horse trailer.
I will head his way next week and see if I can help.
I have no background other than it’s a stock rig with auto, and I’m looking for advice on what to look for.
I’m wondering if his fuel bypass is popping/worn out.
Any other ideas?
Thanks, I’m advance
