Question about 1992 Buick Century
Service engine soon light goes on and off. the car has 132,000 miles on it
Your O2 sensor(s) are fouled. This could be an expensive repair ($200) or inexpensive. Try adding "SeaFoam" ($9) available at Advance Auto Parts and WalMart add to your tank per instructions on the can...(cept you have to drive the car at least 100 miles thereafter).
