If you could get a good picture of one of your plugs and post it, I'll bet someone here could tell you allot just from that. There are some knowledgeable folks on here.

Or better yet pack up your fuel system and send it to Mark Burch Motorsports to have it flowed. I think it is like $125.00 to flow your complete fuel system.
