I have a 99 RL. Has anyone done repairs on their Acura based on these codes. I cannot find specific information on what to replace/repair. Any information will be greatly appreciated.

The 0173 code does not exist as far as I can tell. However, 0174 code refers to the "left bank running to lean." The following items can set this code; insufficient fuel flow/pressure, clogged fuel filter/clogged or leaking fuel line or clogged fuel filter or clogged injector. Also burning lower octane fuel, HO2S-1 sensor going bad and last but not least EGR system flow is insufficient or an exhaust leak.

Thanks. So many possible causes. I just read that the Manifold Absolute Pressure (MAP) sensor may also be a possible cause. They suggested cleaning it with brake cleaner. That's where I will like to start. My problem is, I don't know where the MAP sensor is located on the 99 RL. Any description or picture will be appreciated.
