I have a 96 civic (http://www.automotiveforums.com/vbulletin/showthread.php?t=906594#) ex and I just installed a MSD modified distributor cap, MSD external ss coil, and new plugs and wires. Ever since I put the stuff on it seems like it's missing in the lower rpms. I'm not a master mechanic, but I am quite proficient with working on cars (http://www.automotiveforums.com/vbulletin/showthread.php?t=906594#). Any suggestions would be great. Thanks!

double check the install and make sure everything is seated correctly. also might want to make sure moisture didnt get under the cap and could be shorting it out.

You sure the timing is right? Could it be set too advanced?
