Go to an auto parts store and have them scan for a code. That should give you an indication of what is wrong with it.

None of those lights having anything to do with stalling or fuel filter or fuel pump.
As for the ABS, etc, this is likely due to the wheel speed sensors not reporting properly. While one or more of them could be bad (wheel hub replacement), these circuits are notorious for poor connections, corrosion, or bad wiring due to age.
The wheels speed sensors can be tested before replacing. Start with getting the ABS codes scanned. This will tell you which sensors are having problems.
Before any of this, you should look at the other engine codes and address the stalling, etc first. Scanning the engine and looking at air flow, fuel trim, etc will guide you to the next step. Have you changed the air filter recently?

sounds like your ABS sensor is bad. The ABS sensor controls the trac. control. but it wouldnt effect daily driving. you would only notice it if you slamed on the brakes on a slick surface. the brakes will lock up like they ARE NOT supposed to.

dont think its computer,but you have one for engine and another for abs/trac and then body computer, scan engine codes and go from there,hope this helps.

check the abs sensors make sure they are connected. Also check your wheel bearings if faulty may cause these lights to come on.

you are going to have to take the dash apart. You probably have a short in the connector where it comes into the gauge cluster

Check the 02 sensor and the ignition switc.

Anti-Lock and Trac Off lights are lit on my 1999 Alero, as well. They usually come on after about 5 minutes of driving, but are not always on when I start the car.

ok there is a difference between the check engine light and service vehicle soon light. The service vehicle soon light comes on when a bulb is out on the daytime running lights. Check your bulbs if there is one out and you put a new one in it will most likely take car of problem.
