1996 Buick Park Avenue Two Wheel Drive Automatic

I have a 96 park ave that I am at a complete loss of what the problem is.

When ever it idols the car dies unless you have your foot on the break and a foot on the gas. It will try to idol and then you will see all the gauges drop and the car dies. You have to drop to N and then turn it back on.

I took it to the shop and there they replaced the spark plugs and wires, fixed a gas leak, as well as oil leaking in to the coolant pan. Also tried to replace the computer and alternator but they could not figure out why it dies while idling.

I ran out of money before we could check anything else.

I am hoping you can give me so ideas of what I can check my self and fix my self. Any info would be great thanks.

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.
