Can a faulty O2 sensor cause a reduced engine power fault in a 2003 GMC Sierra 2500 hd

Yes, faulty O2 sensor will change the air/fuel ratio and although a small amount of extra fuel can produce more power, both an excess and insuffcient amount of fuel will rob an engine of power.

GMC 2500 Diesel, reduced engine power??

Just my 2 bits, go through a spring cleaning checklist. Plugs could be fouled up, fuel could be contaminated, you already did the filters. Do you have it chipped or programed? Change the exhaust lately? Do you have the code number? Autozone will scan it for you for free, tell you the code number. Again, just my 2 bits.

I am told the glow plugs heat up in "firing" order, also the Duramax uses a intake air heater to warm the air on cold starts.
