ATTN 85 6.2 gp controller

hello all got a problem with my controller i try to cycle plugs and at end of cycle it does not click off instead stays makeing a shorting sound stops and im able to fire her up. Could it be a bad connection or is controller going bad? Also previous owener has by pass hooked up so should i just let it go bad will it mess up anything else? or bite the bullet and spend the 70 bucks that i dont got . thanks all for any advice: warlocks with help i will be WINNING gotta laugh @ mr sheen
