My sons VW Jetta Wolfburg edition has started to really run bad. It acts like its ready to stall at times and also like its not getting any gas. Took it to Autozone and had them tell me what the codes are that show up on it. They are the following P0304, P1296, P0011, P0301, P0106. I just changed the spark plugs and it seemed to run fine after that for awhile.

Thank you very much for any suggestions.
