If your idle is surging, or your car is dying at idle, you probably have a bad MAP sensor.
The map sensor is easy to find. It will be a grey or black ( black is more common) plasic box mounted with 2 screws at the back left of your intake. The vacuum line to it may also be the problem. it's about the size of an open matchbook. and about a half inch thick. The vaccume line enters from the side you can't see.
If it's not the map sensor, It's most likely the TPS throttle position sensor. It's easy to find. It's on the throttle body.
