When you changed wires, did you happen to re-use the metal shrouds on several of the plug boots? If those were installed backwards, the clips will touch the base of the spark plugs and create a tough to trace misfire.

no i didnt need to use the shrouds because my high temp plugs didnt require me to.

Hooking it up to a scanner would be very helpful in diagnosing your problem. How many miles are on your car. If your getting near 100k it may be time for a full tune up. You can pick up a coil and coil wire at parts distributor like auto zone for fairly cheap so you can roll that out. If I had to bet money on it though I'd say opti.
