p0171 refers to the bank 1 being lean..check the left side of the intake manifold with the carb cleaner while its running. If that passes then change the O2. My O2 went bad a couple weeks ago and gave me a HORRIBLE misfire...one that I've never seen an O2 cause before.

If your not coming up with a specific cyl. misfire than its probably not an injector, but could still be fuel related.
