O2 SENSOR

1991 Buick Park Avenue

Electrical problem
1991 Buick Park Avenue 6 cyl Front Wheel Drive Automatic 46,000 miles

Car would stall (stop running) while driving down the interstate. The speedometer would quit working, the cruise light would flash, and service engine light would flash. I had a friend to check the code and it showed O2 sensor bad. Replaced the O2 sensor and it worked great for two days, now it is doing the same thing again. It really isn’t safe to drive, when the engine stalls it is impossible to steer!

Any thoughts, is the computer bad? Replace the O2 sensor, maybe bad again?
