No, I haven't replaced the plugs. When I bought the car I replaced the ignition wires and the distributor cap. When the coil died I (a couple of weeks ago) I replaced the coil and the rotor. I haven't looked at the plugs and I haven't done anything with the timing.

Do you think plugs could cause the symptoms I was experiencing? The hesitation from a stop and, now, not starting at all? I figured, if it were plugs, that only one would go bad at a time and then it would most likely chug away on three cylinders. Unless it's been chugging away on three cylinders since I bought it and I didn't even know, then a second plug went bad. Maybe.
