my 96 mazda protege idles faster when the lights are turned on. Once the lights are turned off the idle drops rapidly until the car stalls.

STALLING AND DIRTY THROTTLE BODY


You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkal, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still stalls, replace the IAC.
