You show your car as a 2001, however, you probably have a large round connector under the hood, if you do, you will need the round to standard ODB adapter cable to read your codes while connected under the hood.

Also check the terminals in the MAF connector and make sure they are not damaged and are tight.

If you have a CEL on, get your codes read and post back here for comment. Check to see if you have the large round under hood connector as well.
