Answer
William,

Change the air meter if you have not done so.  Clear the code in the computer by disconnecting the battery or use a code scanner.  Once the code is cleared retest and see if the problem has gone away.  If not email me back.  If a code is still present and you did replace the part the computer will still see it as a problem until the code gets cleared.
