Im glad it runs better now.

#7 was black and wet - #2, #6 not far behind.

All of them were pretty wet and none of them looked super healthy.

Also, this car gets several short runs (8 mile or so round trips) from my house and doesn't always get really warmed up. I'm sure that isn't good either for the life of the plugs.

Yeah, that cant help much huh? Take it out and blow the crud out once in a while. See if you get more life from this set of plugs.
Glad to hear its running better.

LOL sounds like the use I get out of mine in the last year. Having twin 11 month olds makes the Camaro a nice boat anchor for a while....

Could possibly have an injector issue- bleeding down and flooding the cylinder at low speeds/light fuel requirements. Under hard throttle it may be able to use some of the extra fuel. Let us know what you find.
