Codes
I got two codes: P0404 and P0405. What all needs to be addressed with these codes? I have looked them up and I want to know how major they are? A while back I had my pedal problem replaced, is there a warranty on it? If so how long? I think I am having that same issue again.

My Mazda used to trip egr valve 1-2 times a year. I bought a replacement, and clean/swap out when that happens. It hasn't done it in awhile. I suggest take it off, and run some carb cleaner through.
