OK, I did the tune up and compression test and am pleased to announce my compression is as good as a new engine! all cylinders are running about 160psi and I've got about 160k miles. I replaced my sparkplug wires, cleaned and regapped the sparkplugs (all looked good), and replaced the distributer cap and rotor. I still need to clean the throttle body though.

It's probably my imagination, but I think I have a little more power. I'll know, the next time I head to the mountains.

Thanks for the advice everybody.

Steve
