Well looks like I'm gona head to the parts store in the morning and see if I can pick up a decent set of wires. I can't tell if the plugs fixed my mis or not. At first I thought so then it started idling rough again after 30mins or so but it could be that short plg wire not getting good connection or I didn't get one snapped on good enough. :/
