It has a Delco Remy distributor and yes the plugs seemed fouled to me. Also there is a lot of crud on the bottom of the engine and it looked like who ever installed the last plugs was just stabbing away trying to put them in and all that crud got on the end of the plugs and shocked hard as rock to the end of the plug. I was surprised that half of them even worked. Put new plugs in. Haven't pulled them yet. She is my daily driver so I drive her all distances all the time. Work is 20 minutes away on the highway, Sister's is about 15 minutes away and at night I have a small business where I pick up stranded bikers and tow them where they need to go so their bikes aren't stuck somewhere over night and they don't have to pay for a flat bed to come out. Maybe 3 or 4 calls a week. Never needed a trailer and the furthest I've taken someone is 40 minutes on the highway. I don't believe the distributor is computer controlled.
