pappa,

These codes indicate a LEAN condition in banks 1&2.

1) Clean your MAF and than disconnect your battery to reset your PCM. If the code(s) come back...

2) Do a search on the word "Lean". The posts will tell you to check for vacuum leaks. (unmetered air getting into your motor will cause a lean condition.)

If you need more help, don't hesitate to post again.

Good Luck,

Bill
