2002 Dodge Stratus R/T/ 3.0 Reads code PO171 Lean on # one bank. Are there "other" possibilities, other than injectors, and if so what are they? Which "bank" is # one?

Injectors are pretty rare. Chrysler has almost no trouble with them. Look for a vacuum leak first. A misfiring cylinder will send unburned oxygen into the exhaust where it will be detected by the O2 sensor.
