Hi all I have a 1998 chevy 1500 zr1 5.7l and it seems to be running rough. when I use my scan tool it comes up as a cylinder 6 misfire. I was wondering if anyone else has had this issue I had all the plugs and wires replaced not that long ago. I was just wondering if its an easy fix by just replacing the spark plug on the 6 cylinder

 

Mine did this in a 2000 model gmc. I was hopping it was just the plugs or wires... But turns out it was the distributor.
