I agree, the economy is bad. We all feel it. As far as the car, take it to a nationally recognized auto parts store and have the computer scanned for codes. Even if the check engine light isn't on there still could be a code. If there is, it will point us in the right direction. It looks like you have replaced most of the things that deal with idle; there are other things to consider. For example, a map sensor, mass air flow sensor. While you're checking for codes, tell your sister to be really careful.
Let me know what you find. Also, make sure you allow the car to run irratic for at least 30 + seconds. Otherwise, the computer may recognize the problem as a random fult that has fixed itself and will not store a code.
Let me know what you find.
