Default Is it time for new O2 sensors? If yes, where to get - Vast Perf? Suggestions and advice appreciated!

Threw this code on 6/17/05
16514 - Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit
P0130 - 35-10 - - - Intermittent

Threw this code on 7/14/05
16534 - Oxygen (Lambda) Sensor B2 S1: Malfunction in Circuit
P0150 - 35-10 - - - Intermittent

Threw this code again on 10/13/05
16514 - Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit
P0130 - 35-10 - - - Intermittent

Car is boosting fine. MAF seem a bit dirty, but no other codes or strange behaviors lately. Note: these DTCs started popping up after I installed my gutted DPs on 6/11/05.

What's the prognosis and how have you guys fixed the problem. TIA for your advice. Yes, I've STFA, but wanted more advice from AW vets.

Cheers!
