It's throwing a new code now. P0420. Could this be caused by the p0300 code or should I treat these as 2 separate problems. I'm taking the car back Monday to the shop and telling them it's never thrown these codes until after I picked the car up from them yesterday. I hope they stand by their work on this one. These are 4 brand new codes I've never had before.

go over all the wire harness, I'm betting something got missed or crimped.
