After starting engine, idles very low, a few seconds later engine cuts out.
This happens several times, even when car comes to a stop or even when in park.
Rev's die down engine stops.
Car does start quite easy for a second orso,
then cuts out again.
No other noises just the idle then engine cut out.

First eliminate all vacuum or air leaks in the system. You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, 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 has a problem, replace the IAC.
