I haven't noticed any misfires or rough running. I just think the truck is a little more lethargic than it was a last year at this time. I did check the plugs which were installed about 14,000 miles ago. They were all good. I did replace the plug wires about a month and a half ago. The truck seemed to gain some power but only for a few days and then it seemed like it lost it again. Maybe it is just me.

Pretty much stock, except for the goofy oil pressure gauge the previous owner installed.
