2) service stability system
what needs to be done?
The diagnostic information from the vehicle needs to be read out, I think you'll find some diagnostic trouble codes that will help to determine what is going on here.
THE SERVICE THE STABILITY SYSTEM IS THE LEVELER IN THE REAR SUSPENSION. THERE IS A LEVEL SENSOR BEHIND THE LEFT REAR TIRE. IF YOU GO TO PONTIAC THE PART IS ABOUT 235.00. IT BASICLY LEVELS OFF THE CAR IF YOU LOAD UP THE TRUCK AND BACK SEAT.
