89 GTUs revs up and down at stop

Thanks to everyone for the suggestions. At this point, I cleared the codes and started the thing up. Everything is now fine, no changes made. It's possible that the computer just glitched and shut the pack down? I guess I'll just have to watch it for now.

It could be just an intermittent glitch...
Remember, your car is approaching 25 years of age.
Mazda isn't known as the best in reliability on top of that.
The ECU stores error codes until you clear them out.
All it needs for an error code to be stored is just one wrong signal...
Glad to hear you solved it pretty easily.
