engine stulmbles

Hey I have a problem, whenever i accelerate especially around 4400 rpms(vtec engagement point for intake) my engine stumbles. I replaced plugs around 3 months ago, I replaced plug wires around 2 days before this started happening, and i just changed fuel filter yesterday(so it's not that). Oh yeah and my plugs are cloudy white at the tip. Some help would be appreciated. Thanks:)

there was a page on how to read your plugs,just cant remember where it is, but i think the legend for reading spark plugs goes:

white = lean
gray = stoich
black = rich

you could be running lean, so check your fuel pressure, and the cleanliness of your injectors to see if there are any problems there.

Well go through the rest of your spark system first...Check your distributer and coil. Followed by your injectors.
