Default Please Help... Misfire

UPDATE I got these codes from autozone P0301, P0401, and P1443 (cyclinder 1 misfire, evap, and egr) I bought plugs today and was going to change them, but got to thinking... This started happening right after the truck started running hot for a few days... I also live in FL so the temps always hight anyway.... Maybe one of the vacuum hoses now has a crack?

Hey guys... new to the site! I have an issue thats driving me crazy. I have a 95 ranger 3.0 and its misfiring... It has a rough idle at times and then at times its fine.... Sometimes it runs ok when driving, but most of the time its skipping, shaking, misfiring and all that fun stuff. This is the third time it has happend. Ill change the wires/plugs and it will run just fine for about 3 months and then back to same issue. Ill change the plugs/wires again and its fine, then 3 months later, same issue.... Any ideas on whats causing these plugs/wires to go bad so quick? Any help would be greatly appreciated! thanks!
