hi, today i started my car and it idles a little rough for about 5 seconds then was fine, then the check engine light came on and was flashing, p0303 and p01399 came up when i checked it at autozone. I cleared it and drove home about 5 miles and was fine. Any clues?? New plugs ngk iridium and ngk wires a few months ago, 9 month old dizzy.
