OK, here's the latest. I managed to drive it to town to the local AutoZone. I had them run the diagnostics on the CEL. He told me it said "cylinder 4 misfire" (or something very similar). Recommended I try new plugs, and if that did not work, replace the wires. Well, I did both, but to no avail. He said after that I should consider replacing the coil pack.

Before I spend about $85 and an hour or two of labor on this, is this what you folks would recommend? Any other ideas? Is there any way to test the coil pack before I just blindly replace it (as it would seem my plugs and wires were probably OK to begin with...)

I'm thinking that whatever it is can't be too major if the car can make a 20 mile round trip without running hot. (Then again, maybe I'm an idiot for trying it...)
