99 legacy outback 2.5, 235k, recent new head gaskets, original catalytic converter,
have a replacement autozone gascap, that has been in use for prior 3 months, without any codes
after the HG, got a P0420 followed by 2 PO440's, so there are currently 3 codes in my obd reader, listed as fault 02 and pend 01
P0420 Catalyst Efficiency Below Threshold (Bank 1)
P0440 EVAP Emission Control System Malfunction
Thinking gas cap probably ok since no codes since I replaced it a while ago, and probably next step go to smog check place to see if their analysis shows I have a bad cat converter.
Any other ideas to try?
If bad cat converter suggestions where best to get a replacement?
