Fast Kracker

I have an 83 gl wagon. and i have dreams of going camping and off roading in it. there is one minor problem, i cant keep it running! I'm not a moron, if you tell me what to fix or change on a car I can get it done. ask me to diagnose anything and we will be standing around for a while. I'm looking for some one who lives near seattle and is willing to share their time and info on a verry worthy wagon.
