Rough idle is a very common problem on 4 cylinders, but I believe the 98 Regency has a 6 cylinder in it, right?
Sometimes the coil packs get iffy, and sometimes the EGR Valve gets a leak in it causing a rough idle.
When the accelerator pedal is depressed, it can change things so that the engine seems to run smoothly.

The OBD-I scanner can help to diagnose the problem, if anything is out of specifications on the engine in question.
The owner will have to find a technician that has such a scanner.
