Jim,
Sounds like the idle position sensor. Easy to check; with the engine off,
open and close the throttle. If you hear the switch clicking there is a 93%
chance that it is working.  To be absolutely sure, follow the procedure in
the Bentley.
The idiot lights are  coming on because the alternator is dropping below
it's minimum RPMs.
