Replacing spark plugs- better mpg?
I have noticed after a set of my plugs fowl with carbon, my highway and city gas miliage drops significantly!
Normaly, I get 20 mpg highway, im getting 16 mabey right now.
I get 15 city, and get 10-12 right now.
Replacing them puts the numbers back up to normal for a few thousand miles (6k+).
Anyone else notice this?

Banned. I got OWNED!!!
If they're not sparking well and not giving you a good burn, then your engine is going to have to compensate by throwing in more gas to get the same acceleration result as if you had good plugs.
