Truck runs rough when stopping/ stopped
'03 2500HD 6.0l Recently, when I am coming to a stop, below about 15mph, my volt meter will dip down below 12v and the engine idle feels like it is struggling. After a few seconds at idle/stopped, voltage returns to @ 14v and all seems fine. Situation is worse w/ A/C running. The alt was replaced last year with rebuilt one when i was having same issue, it corrected the problem until now. I replaced the alt w/ a new one but, am still having the same issue. The battery was replaced last year. Any suggestions?
