Thanks, guys. I did try disconnecting the battery so far. Didn't make a difference, or maybe I needed to drive around for a while before it changed. I'll have to try again and see.

Here's more info:
It used to rev past 6500 in neutral no prob. This is also happening in 1st and second gear too (haven't tried in the other gears for safety reasons).
The car is completely stock under the hood.

A friend at a honda dealership says the system might not be used to the bigger spark with the new plugs, and it might be limiting because the EGR valve has carbon buildup (it's never been cleaned or changed on my car, and this is the first time I'm changing the sparks). Supposedly there was a service bulletin about this which he's trying to find.
That sound right to anyone? Thanks for the suggestions.
