Default 3 codes

Hey all again!!

Well had the ses light come on the other day took my car to advanced and had it scanned and her are the results-p0134 p0420 p0442.

I am assuming that 134 and 420 are a result of my new high flow cat,although the 134 code is due to a bad connection I had to mess with about a year ago and the other day I was checking my back plugs so I might have loosened the connection to bank 1.On a earlier post I did I was getting this code and eventually figured out that the connector was broken so I direct wired it and the code went away.

My concern is the 442 code small evap leak,and I wonder if this is the reason I have the chugging going on in od going up hills or slight acceleration.My question is where to look for the leak at, could it be as simple as the gas cap?

The 442 could be a loose vacum line on the EVAP purge valve?
Check the valve under the hood, behind the egr valve at the back of the motor, also check the electrical connector.
