Figured I'd update. Actually, I fixed the problem about 3 weeks ago. It turned out to be the ignition module after all, bought a new one for 80 bucks, installed it, good to go.
Of course, now problems are arising again. The car is shuddering whenever I accelerate. Seems almost like its choking and acceleration is nil. If I just drive slowly and accelerate slowly, I'm fine. But even if I try to "get on" the accelerator a little, it'll accelerate like it's missing a couple cylinders and begin to shake.
Sooo. Time to check the spark plugs, wires, etc. Troubleshooting is ever-so-fun. 174,000 miles out of the car so far, so I guess I can't complain too much.
