Thanks. I was thinking about it today. I've been thinking it was something electrical the whole time. Which it was. Got a repair manual and turned out to plug wires were crossed. But its still doing what it did before so I'm thinking it's the fuel. Cause my dad just drove this truck everyday. Never did anything to it but put gas in it and go. I've replaced the regular stuff. Coil packs, plugs, wires, air filter, oil, oil filter, and now I'll try some high oct. gas and a new fuel filter and see what it does. Thanks again guys. I'll give you an update on what it does.
