I was able to open up the throttle to clean the walls under the valves, but in doing so I saw that while pushing the throttle all the throttle body valves on the right side of the engine were not opening as far as the left side of the engine. Makes me wonder if this may be the cause of the rough running issue or not. I'm no engine guy but I would think the right side should be opening pretty much the same as the left. In the photos below show two throttle bodies (#1 is the left rear side and #5 is the right rear).
