Having problems with your 1999 Pontiac Grand Prix ?
My ABS and TCS "idiot" lights keep coming on. is there a sensor that needs to be replaced or is there something really wrong with the car? Any checks i can do to see what the problem might be?
You can have someone run a scan on the car to see what the trouble codes are. It could be a wheel bearing going bad.
