Muzzy said:If you fried a cylinder, the plug will look either melted or physical damage. The color of the plug under normal conditions would be light brown to almost white. Other signs would include excessive blow-by (you would notice by removing the crank case vent tube from the intake), silver or metal particles in the oil, and obvious low cylinder compression (use compression test gage). A leak down test is the best option to verify cylinder health.
It sounds like it is more likely an electrical issue as stated earlier. Check your plug wire and connections. I use dielectric grease on my electrical connections. Make sure wires are clear of moving parts (steering components) or exhaust manifolds/headers. A grounded wire because it was burned through will show misfire codes.
Good Luck
