Ken Cappon, there are a few causes for the P0131 code:

- Faulty Front Heated Oxygen Sensor (HO2S) Bank 1

- Front Heated Oxygen Sensor (HO2S) Bank 1 harness is open or shorted

- Front Heated Oxygen Sensor (HO2S) Bank 1 circuit poor electrical connection

- Inappropriate fuel pressure

- Faulty fuel injectors

- Intake air leaks may be faulty

- Exhaust gas leaks from [http://engine-codes.com/p0131_pontiac.html|here]

Replacing the Front Heated Oxygen Sensor (HO2S) Bank 1 usually takes care of the problem.
