When you say it wouldn't turn over, do you mean you turn the key and nothing happens? The starter doesn't turn the engine?
Maybe a bad starter, or bad ignition switch?
There are so many problems that can cause misfires. I have been fighting this on my '99 GLS for around 8 months now.
If you have a bad speed sensor it should throw a code, and you will have problems with your speedometer. I replaced mine recently as the speedometer would stop working sometimes while going down the road. It was very easy to replace.
Use a spray bottle and mist the coil with the engine running and see if you get your rough running to return. You can also mist each plug wire.
