The check engine light in my 2005 V6 is is on with the following persistent trouble codes:

P0135
P0141
P0161
P2197

I tried replacing all four oxygen sensors (I know; bad idea) with new Motorcraft sensors, but the codes remain. I was able to clear a previous trouble code (can't remember which) with a new aftermarket EGR valve.

I'm assuming that the problem is either somewhere in the electrical system or the PCM. Can any of you brilliant folks recommend other fixes I should attempt before giving up and dropping it off at a dealer? I also checked fuse 47 and it isn't blown, but should I check others? Thank you.
