I would perform a cylinder balnce test. You can unplug individual injuctors or coils to find cylinder thats missing. The ones with no change are the problem cylinders. Injectors are probubly plugged if filter was plugged.

Take a spray bottle with a little vinegar and water mix in it and spray around the cops and boots while engine running. Then check again for codes. Sometimes when a cop is about to go they don't output a code. The water will help it along. After that you will probably want to look at all the rest of the boots, or even just replace them.

If you're going to spend the money, go aftermarket. Newer, stronger pipes and freer flowing muffler sounds better than the stock, restrictive system.
