"System lean, bank 1" First, I would suspect a vacuum leak. The engine is getting unmetered air. Check for disconnected vacuum lines, cracked rubber/plastic vacuum lines on the engine, on the firewall, in the engine compartment.
Depending on the year of the Buick Century it may have vacuum controlled heater blend doors. These use engine vacuum to move the doors that control where the heat is directed. If one of the vacuum lines has a hole in it, it would cause the engine to run unevenly due to the vacuum leak. Check the vacuum lines and listen for air leaks. You can also try spraying the vacuum lines with *small amounts* of carb cleaner, if the engine idle goes up when you spray a particular spot there is a vacuum leak there.
Most of the vaccumn lines are located on the engine itself around the intake.
