I have a ford 2003 windstar that was running very rough when cold and almost stalling. engine light came on. went to autozone and they read the codes for free and told me it was running lean on Bank 2 also. i came home searched for the O2 front sensors online using the info autozone gave me. there are 2 front sensors on my car that need to be replaced at the same time. look for ones that have a direct plug in and don't need wire splicing. the ones without the wiring harness are cheaper but more of a pain, i think.
they were fairly easy to replace. getting access with the wrench was the worst. reset the light by disconnecting the battery for a few minutes. seems fine now and the light hasn't come back on.

The O2 sensor is a measure of the Oxygen in the exhaust gas, so there are 2 typical locations for them.
The most common place in directly on the exhaust manifold. The second is usually under the vehicle, on the exhaust tube just in front of the catalytic converter, usually on the top side of the pipe where's it's most inconvenient.
Follow your exhaust piping from the engine to the tailpipe and you should find them. They're the only things on the exhaust with wires running to them.

B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter
You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks
