Re: rough idle, really bad
Sounds like a misfiring/timing issue. I'd start with a the standard tune up if your mother didn't take care of it. Stalling could also be caused by bad coils if it's indeed the ignition system as I suspect.
Check these (not necessarily in this order): Ignition system, air delivery system (esp TB/MAF/IAT), fuel delivery system (clogged injectors, fuel pump).
Also note that the batteries in these WK's have been known to exhibit CRAZY symptoms when the voltages vary even slightly. Make sure you get yours load tested.
