My Seville SLS 96 had rough idle problem for about 6 months. Cleaned Throttle body, no improvement. Checked using timing light and noticed some interuptions in the sparking. Changed wires with AC Delco, worked perfectly.

Good call - put this in your tool box. It may come in handy. The wire from coil to plug sequence is critical. Google "waste spark ignition".
