MisFire Help

Ok, My car was mis firing real bad, i checked it out and found it was a bad coil pack. I replaced the coil pack, put Bosch Wires and plugs in it. and it is still misfiring, not as bad as it was, but it is still misfiring, can someone tell me what i can do next, i dont know a whole about cars but just enough to get buy.

thanks

maybe you didnt gap them right also if there was any oil or crap all around pull your plugs out again clean the area up and make everything clean.

i had a buddy of mine who works for mitsubishi(mechanic). put the plugs and wires in at the time, when we found out it was the coil pack, everything is hoked up right, im thinking the injectors might be dirty maybe? is their a way to clean them.
