O'reilly's pulled these codes off of my 2007 Fit 177k.
A couple weeks ago it started jerking and wouldn't accelerate past 25/30mph and started knocking. Mechanic ran a a diagnostic and all it pulled up was the P0420. The back flow test showed it wasn't clogged, all
Plugs and c-packs are new, the o2 sensors are new.

It seemed fine until Friday. It started doing the low acceleration and knocking again and then straightened out. 30 min later, sitting in stand-still traffic, it just died. I took the key out and started it back up and it was ok. Then today it started knocking and doing the jerking. So I took it to o'reilly's and they pulled all of these codes off it it. The knocking sounds like it's by the left front tire.

Any help as to what they could mean and what I'm looking at cost wise would be helpful!

Just a wild guess here: Check the 02 sensors, maybe they were switched.

 

Was just checked. Everything is fine there.
