Did you check the gap on the plugs? Most plugs are pre-gapped, but once and awhile they are off. Recheck the plug gaps to be sure they are correct.
Did you tighten the plugs enough? General rule is finger tight and then use a wrench to tighten them another 1/2 to 2/3rds of a turn.
Did you buy the correct plugs for your engine? Not only should they be the correct number plug, they should also be the correct heat range for your engine. I doubt if that's the problem, but if all else fails, ask your local auto parts store to look up the correct one for your vehicle.
