P0174 is lean bank 2 (driver side) there are 2 vac hoses that go on that side. one is from the brake booster check that line real good. Also how do your brakes work? You can get a lean code from a bad brake booster too.
The other vac line is for your vapor management system, a bad vapor management valve can also cause that code. There is a vac line that goes from the plenum to the vmv on the firewall, check that one good too. Then follow the metal pipe that goes back to the tank and there is a small section of hose in the wheel well behind the front tire on the driver side. That piece takes a beating from road stuff, if it is flaky change it.
Last suggestion is on the passenger side by the starter solinoid there is a "T" and another short piece of vac hose check that guy too. After the "T" the line continues to the box behind the battery, check the box for cracks.
You put 1131/1135 as the other codes I'm guessing 1135 is a typo and you meant 1134. Those codes mean the rear O2's aren't switching, the PCM is trying to trick the front O2's out of the lean condition. Fix the 174 and I think the others will go away.
Good luck and post back.
