Fuel system problem on my LJ
So we been having problem with the '04 LJ with 65k miles. It loses power after it warms up. the mechanic got the following codes: P0432, P0455, P0300, P03002 and P03005.

Do you think this is an 02 sensor problem or, god forbid, the catalytic converter(s)??

Thank you in advance for any ideas.

Reset the codes if not already done by disconnecting the battery for a couple minutes. Then see if any or all return. They are all over the place, P0432 is cat. related, P0455 is evap system leak (often the gas cap not sealing) & the P3xxx are engine misfire related. (random, cyl #2 & 5). I don't think any one issue will cause all those codes. Has your CEL been on for some time or did it just come on?

You can check your own codes by turning the ignition (without starting) on-off-on-off-on & reading them in the odometer display.
