Lagging or missing when hard on the gas

When im gettin on the gas hard up near 4k rpm or higher it sometimes feels like its missing, or lagging bad. I replaced the knock sensor and collant temp sensor when I bought the car. Only thing I can think of is when it was running like that it was pig rich and now my plugs need to be changed. Any other thoughts?

Hmm Havent checked that, when I got the car it blew due to the 2 sensors it needed. Ill keep my eye out for what the fuel econ is now. But i have my foot thru the floorboard most of the day. The NGK v-powers are the best way to go. Cheap and the best in my mind. There is a sticky on them in the need to know forum
