I tried the vacuum leak test and it made no difference in the way the engine ran. Perhaps it's not a vacuum leak.

On a hunch, the next day, (today) with the engine stone cold, I decided to pull the plugs and check them out.

They all looked dark gray, except one was black (#8)(see picture below) and one was super clean white (#6). (see attached picture). I put it all back together and than decided to check the condictivity of each while. When I pulled the one that had the wire plug, the boot came off and the metal inside conductor stayed on the plug. wire 7 and 6 were both 1.9 Kohms) Maybe it was a bad crimp?

I plan on putting in new wires, new rotor, cap and plugs. I had the Keith Craft wires, does anyone know what type they are? I was thinking about going with Taylor, or MSD wires. Any suggestion on thickness, spiral, etc? (I have an MSD 6AL2, MSD billet distributor and coil)

thanks!

ps. do you think this could be a bad wire, or a valve train issue?
