Question

For a 2003 Nissan Frontier XE 3.3L V6 getting code P0171, would fuel injector cleaner help?

Answer 1

It's possible, but very unlikely that cleaning the fuel injector will fix the problem. If there are no intake leaks, the problem is either a bad front oxygen sensor or mass airflow sensor.
