Replaced catalytic convertor but emissons are still too high.

Incorrect fueling, could be the maf or possibly an injector is blocked and a bad spray pattern.
I would get the garage to put a wide band sensor in the exhaust and read the exhaust gases, you should be seeing approx 14.7:1 ratio
Also code read for stored codes
