1999 Subaru Legacy Outback 30th Anniversary

I have a 1999 subaru legacy outback. I had the check engine light come on codes reading P0303 and P0304.

I have changed the spark plugs and spark plug wires as well as the ignition coil. But the problem has persisted. Any suggestions? The car has lost a lot of power and is rattling while it idles.
