Is it common or normal to foul out a plug after swapping intake manifolds? It might have been like this before, but I doubt it because it was running good and the plugs are only a month old. Although, it was running good after the install too, just not as strong as I had hoped. All of the plugs had a weird coloring to them, I guess from the coolant and oil that got into them. But, number 8 was black as could be. What do you guys think it's from?
I was running NGK's, I just put in a new set of Autolite 25's. I'm going for a test drive, I'll let you know the results when I get back.

new plugs are your friend. The car idled pretty good for running on 7 cylinders. I need to get some headers before dyno day.
