Question about 2004 Pontiac Grand Am
I just went through the same problem with the three lights. I found out mine was the wheel speed sensor, in the front right wheel hub. I replaced it as there was a humming sound coming from the right (sounds like a loose wheel). It ended up being bad bearings which I just tripped the warning. My buddies code reader would not bring up any info on the lights, they are gone now with the new hub.

The problem is probably the wheel hub bearings and it is more that likely the front. I had the same problem a few weeks on my 00 grand am gt. Connected the car to the tester it gave me a code for left front wheel bearing. I replace both wheel bearings because i figured what the hell they both have the same amount of miles on them. Taaadaaa no more lights!!! Hope this solves your problem.

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

If you had the car scanned with a generic OBDII code reader (Which is what they use at all the parts stores) this is probably why it is not showing any codes. You have "Vehicle Specific" codes. This means that the problem with your Check Engine light is not a problem that will generate a "generic" OBD code. A generic OBD code reader will not read codes from your Antilock Brake System or your Traction Control System at all... You need to have it scanned professionally by someone who has the proper equipment and software to access the Controller Area Network (CAN) in your vehicle.
