Is it a serious problem that my 'Service Engine Soon' light comes on while the engine is runing at low rpm's, but when I start accelerate the light goes off.

Re:1991 Buick Century 3.3L3300v6 code N engine..

I have the same engine and year of car. My service engine soon light came on and off after i replaced the fuel pump. Dealer Ran on Tech 1 and found my O2 sensor was on the fritz. They said go to Autozone and get an oxygen sensor and the light will correct itself. the part cost $20.00 plus the tool and taxes so under $40.00 total.

to this day that light has remained off and i normally get 300 miles on a full tank of gas...

my car has 184,000 miles on it!!!!
