In reply to your PM.
It is best to keep answers and question in you post so everybody can help.
We need to know what engine.
The code 44 you mention in pm e mail is not need 02 sensor code.
Codes do not say replace sensors, but to check it out.
Code 44 is lean exhaust code.
On a 4.3 or 5.7 engine
Fuel pressure bad wiring on 02 sensor or weak sensor or exhaust leak or water in fuel or clogged fuel filter.
Also make sure the tank has over a 1\4 tank of fuel.
To check fuel pressure hook a fuel pressur gauge to the scrader valve test port if it has one or hook inline at the fuel filter and be sure to check the fuel filter.
Post back fuel pressure readings and what engine.
