001110 - EVAP System: Very Small Leak Detected
P0456 - 001 - Upper Limit Exceeded - Intermittent - MIL ON

001056 - Catalyst System; Bank 1: Efficiency Below Threshold
P0420 - 002 - Lower Limit Exceeded - MIL ON

could it be EGR hose leak? or does that throw its own codes? Someone else had that problem and it was a simple fix but nasty to get at.
