Most of the solutions to this problem involve the battery and PCM (powertrain control module). Battery might be going, or corroded terminals making for a weak contact. This seems to be a common complaint with this vehicle, and most solutions involved replacing the battery or cleaning the terminals. Aside from corroded terminals, if you have worn motor mounts, it might cause the motor to shift enough the negative ground for the battery loses contact, which in turn causes all sorts of problems with the PCM which affects the IAC (idle air control valve). Even if the battery and connections are fine, the IAC might need a good cleaning or replacement.
