miss-fire

Ok so I changes my plugs and wires, hoping to get rid of this miss, granted the car runs alot better now that I put the 606's in with new wires but there is still a problem and cant figure it out. It isnt throwing a code so maybe you guys could give me some insight.
 


What is the year of the car and any mods? Also, give us symptoms other than misfiring? Normally if its a large number of misfires than a code would be set. Are you talking about 2-3 misfires? Cause its normal to have a few misfires.

it is a 2000 gp gtp, no mods really other than the cat and u bend delete and zzp sim. how rough the engine is running, seems like alot of shake. and I every 3-4 second sounds like a mis listening from back of car
 
I take it the engine was running rough before you did plugs/wires as well? Have you checked into other typical maintenance like fuel filter? Could be a clogged cat.... or could just be engine/tranny mounts are shot.

Im a complete noob when it comes to this stuff, I dont know where the fuel filter is, and I have no cat as stated above.
