Re: rough running at high engine speeds

The plugs are Champion UY6. I pulled one of them yesterday thinking I'd replace them since I was grasping at straws with this rough running thing. I've attached a picture. I don't think it looks bad. When I bought the car I noticed a lot of black soot near the exhaust pipe on the garage floor. The mileage was pretty crappy so I did a little research and found that service counselor on the swapped manifold gaskets and indeed mine had been swapped. So I corrected that and I did notice a little bit better gas mileage.
