Chris, The lights stay on while the car is running. They won't go off and I need to get it inspected soon. Lestee

ABS and Trac OFF usually indicate a dirty or faulty ABS wheel sensor. You'll have to scan for the codes to see why the check engine light is on.

the abs and trac is the wheel speed sensor, you will probably have to replace the hub if it is anything like it was on my grand prix, good luck!

I have the same problem with my 2001 chevy impala. Car runs great! Replaced the maf and map sensor as I'm getting code p0102 I believe. You think the computer module under the air filter is bad maybe? I need a quick fix.
