Before I changed the hose the codes were 15, 17, 23, 24, & 41. Now they are 17, 23, & 41.

The battery is 09'.

Have the battery check for voltage drop as well as condition. If it erasds 12.4 with a vom it's probablby not that good. Check your fuel pressure 30-36 psi with vacuum hose disconnected at pressure regulator. You have to check for poor conections at O2 sensors, or a bad injector or cloggedfuel return line to tank. You shold really have a pro look at this as this can be multile things. Also next time send data of engine size which you didn't
