So I was driving down a two-lane highway tonight and hit a severe unmaintained part of the road on the passenger side. Can't tell if the suspension bottomed, but the car instantly felt like it had a misfire. Upon arriving home, I ran the OBDII and pulled these codes. 4 of them are fault codes and 3 of them are DTC.

I can't imagine why the entire rear bank would throw a code simultaneously. The car still runs but has a very noticeable misfire. I figure if 1, 3, and 5 are all misfiring, the car wouldn't run, so it seems like a partial misfire, but is isolated to the rear bank. Is there any single component that could have been shaken loose or jostled by hitting a bump in the road? Checked most vacuum lines and ignition coil wires to all 6 cylinders, all intact and functional. Any ideas?

UPDATE: So I ran the OBDII again today with the car running, and pulled 11 codes this time. I am now reading P0303, P0115, P1300, P1310, P1320, P0300, P0301, P0303, P0304, P0305, and P0306. I am utterly and completely baffled by how I can throw this many codes just from hitting a rough spot in the road, little bit ridiculous if you ask me. If anyone woith some expertise could shine some light on this, I would be grateful to say the least. Also, unplugging coils 2, 4, 5, 6 all make the idle drop, while coil 3 does not affect it at all. I still haven't pulled #1, but am wondering what this could indicate. Since basically every cylinder is showing a misfire, is there any one component or section of the harness that corresponds to the entire ignition system?

Start looking for broken wires. The ecu is behind the glove box, look at those wires too. Perhaps something heavy fell out of the back of your glove box and bashed the ecu harness.

I'm thinking wiring problem as well. Check all the engine harness grounds you can find and sung them down. Theres one at the back of the intake near the firewall thats difficult to see. Check the one near the coolant temp sensor on the intake, it grounds to the body near the RF strut tower. Check battery cable connections at battery and battery cable ground to the engine bell housing.
If that don't fix it you might have to start with replacing the Coolant Temp sensor (ECT).
