bank two is on the drivers side. cylinders 1234 right side, Bank 1, 5678, bank 2. you have something like a vacuum leak effecting one side only. Not all code readers come up with all the codes. Its possible you have other codes possibly on the bank 1 side also. If you have a K/N filter it could of deposited oil on the MAF sensor on the intake there or you may have a clogged air filter. . If you really only have one code for one side you may have an intake gasket leaking or the egr may be stuck open a little which could effect the idle quality.

SOURCE: Code #P0171 & code #P0174
The most common problem on a Ford with these codes is deteriorated PCV hoses. Check the hoses from the PCV valve to the intake manifold. Pay special attention to the rubber elbows. They often crack on the inside curve and the crack is hard to see.

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.

Ther is a air Idle control valve located on the side of the throttle body. unplug it remove it spray it and clean it with carb cleaner replace it plug it back in and you will be a Happy person again.
