Honda Repair: Honda Civic Ex Distributor cap replaced, spark plug gap, spark plug wires

Question
Hey Travis it's lougan again. I found the problem with my modified civic was a coroded distributor cap, I replaced the cap and it's running smooth at driving speeds but runs rough at idle still, any ideas?

Answer
Lougan, hmmm... Could not find your original ? but i think i remember. Did you replace the distributor rotor too? Rough idle can be a lot of different things to check. Spark plugs, spark plug gap, spark plug wires, timing, fuel filter, or an unplugged or cracked vacuum hose.??
