Sounds like ignition problem - I would first check the plug wires carefully for cracks, routing problem (flashing to engine), and incorrect order, and if all OK then check the plugs for contamination/incorrect gapping.
2 different problems
check engine light = need to have scanned
2 anti-lock and trac light are linked and could be related. yes spining tire can cause trac light to come on
WHEN BOTH ANTI LOCK AND TRAC LIGHT ON YOU HAVE PROBLEM IN ABS BRAKE AND TRAC SYSTEM.THE DEALERSHIP HAS TO FIX THEY HAVE DIAGNOSTIC EQUIPMENT TO WORK ON IT.THE ONLY THING YOU CAN CHECK MAKE SURE ALTERNATOR OUT PUT VOLTAGE WITH ENGINE RUNNING IS 13.5 TO 14.5 VOLTS.BECAUSE IF ALTERNATOR OUT PUT LOW BOTH LIGHTS WILL COME ON ALSO CHECK THE ABS RELAY.
CHECK ALTERNATOR OUTPUT.MAKE YOUR VOLTAGE OUT PUT IS 13.5 TO 14.5 VOLTS.IF NOT ALTERNATOR BAD IF ALTERNATOR GOOD THE DEALERSHIP HAS TO HOOK CAR TO DIAGNOSTIC TO CHECK THE ENGINE PCM CONTROLS AND ABS BRAKES AND TRAC.SYSTEM.REASON I SAID ALTERNATOR BECAUSE I SEEN ALTERNATOR GO BAD UNTIL IT OUTPUT WAS LOW CAUSING CHECK ENGINE LIGHT AND ABS LIGHT TO COME ON.
You need a new wheel bearing, This also happened to my olds alero, make sure 2 jack up each tire 1 at a time and pull back and forth on them checking for play, once you have found the 1 that has play or wobbles that is the 1 that needs a new wheel bearing
Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the Check Engine, Service Engine Soon, ABS Or TC lights to tell you that there is a problem and you should have the car diagnosed and repaired. I would take it to a service center you trust and let then come up with a solution. Sometimes a problem in one system will turn light on for other systems that communicate with it, but it doesn't mean there is a problem in all of the systems.
This is related to a problem in the BODY CONTROL MODULE, the GM dealer can test this module and give you some idea of the repair cost, this is a common problem on all newer GM cars.
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.
