I have 2003 alitma 2.5l.

I'm getting PO420 and PO507 engine codes.  The idle fluctuates in
neutral from 1000 to 1800.  Also while driving if below 2000 rpm it
will bounce between 1500 and 2000.

Anyone have any ideas?

there is a recall for this problem. It calls for a pcm reflash and a
idle relearn. Call the dealer.
