I finally resolved this issue. After running a full tank of gas through it, I pulled the plugs again and #2 was clearly not firing properly as compared to the other plugs. I did a compression test and sure enough, I wasn't getting compression on that cylinder. I pulled the valve cover and investigated the rocker arms. One of the rocker arm shims was somehow out of alignment. Must have been me when I was getting the rockers all shimmed properly. I filed to make it receive the rocker arm smoothly and reinstalled and now my issue is resolved! Thanks for the replies.
