2002 Pontiac Bonneville V8 Front Wheel Drive Automatic 98000 miles
My " service engine soon" light went on so I got the computer readout on the problem which was in the gas cap. I tried to turn off the " service engine soon" light by disconnecting the + battery cable. Instead of going off--the rest of the waning lights went on (brake, trac control, abs, etc.) How do I turn them off? Also I have owned the car 20 months and I had to replace the gas cap two times already. Is there some specific defect with Bonneville gas caps? What gives?
