1993 Buick Century 6 cyl Front Wheel Drive Automatic 160, 00 miles
Our Century will shut off its engine if we drive for many hours in hot weather (100+ degrees). For example, it did this driving from Yosemite to San Diego, and again driving from Mammoth to San Diego, both times through California's central valley in summer, which was over 100 degrees F. Both times the engine shut off after several hours of driving (we would start in the morning when it was cooler, the engine would shut off after the air temperature was over100 degrees). The engine was not overheated, the temperature gauge read normal. The car was running perfectly before it shut off. It would start up again after sitting for 20 or 30 minutes, then would shut off again after less than 1 hour of driving. Each time this happened we checked the car when we got home and discovered the O2 sensor was blown. I am wondering if there is something else that is causing the blown O2 sensor and engine shut-down.
have the same problem?
