Hey everyone, new here first post hope someone can help. It's a 1999 Grand Prix GT 3.8 and I had the codes pulled and here they are P0449, P0440, P0102, P0141.

P0449 - The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid.

P0440 - The PCM has determined that a malfunction exists in the evaporative emission control system.

P0102 - The PCM has determined that the mass air flow imput is lower than expected for the current engine operating conditions.

P0141 - The PCM had determined that a malfunction exists in the heater circuit for oxygen sensor 2 in bank 1.

Any info on this would be greatly appreciated.

Your MAF is bad, your EVAP solenoid is bad, and your rear O2 sensor is bad.
