I had the exact same issue with my '92 3.9. I took it in two days ago,
and indeed the dealer told me that the AIS motor (Automatics Idle Speed?) was
gone. They let me know even before running a diagnostic. Apparently it is
a really common problem. They had to R&R the throttle-body as well to
clean up all the carbon that had accumulated. It had been a problem for
about 6 months. The part was about $80 Canadian. It made all the
difference in the world!
