Not much to go on:
CO: 0.34% FAIL - possible catalyst deteriorating OR mixture too rich
HC: 409PPM FAIL - HIGH, maybe leaking injector or compression loss?
Or old spark plugs, maybe fouled by the oil usage?

Do you have the other readings from the test? Like CO2, O2 and lambda-number?
What are the readings at idle? (Also include CO2, O2 and lambda-number if available).
