I replaced Bank1 and bank 2 o2 sensors aft of converter. When I checked system with my scanner the first time code 0158 came up again. Checked all vacuum lines and wiring I could not find any defects. Replaced gas cap and air filter. Checked scanner again now I have 2 codes P0158 bank 2 sensor 2 and P2096 fuel system too lean bank 1. Any help would be appreciated.

Hi,

Since you are getting lean mixtures, chances are either you have a vacuum leak (which you have checked), low fuel pressure, or even an exhaust leak before the catalytic converter.

First, here is a link explaining how to locate a vacuum leak:

Next, here is a link that shows in general how to check fuel pressure:

Here are the manufacturer's specs for fuel pressure:

Fuel System Pressure

FUEL SYSTEM PRESSURE

400 kpa ± 34 kpa (58 psi ± 5 psi)
