Question about 1991 Buick Century
I'll try and help with a few of your codes, code 12, will show if the diagnostic term is grounded to access codes, it will show any time that is done and the engine not running, all other codes will show after. The 26, 27 codes have to do with the engine over heating or a coolant sensor. #44 has to do with you Ox sensor, indicates a lean running condition. Pos. due to engine running hot. .
