P0171 P0420 P0430 - Little enging power - 03 Expedition

The 2003 Ford Expedition 4.6L 2WD idles fine when cold at about 1000 RPM, but upon warming the idle drops to 700 RPM.  When the throttle is past 1/3 the power flattens out.  The Freeze frame data from the past 5 times the Check Engine Light came on shows the following items (results side-by-side):

P0171  =  System too lean (bank 1)
P0420  =  Catalyst System Efficiency Below Threshold (Bank 1)
P0430  =  Catalyst System Efficiency Below Threshold (Bank 2)

I had just replaced a bad fuel pump and filter.  The two hoses going from the exhaust to the EGR EVP keep blowing out when under a full load, perhaps the catalytic converter is shot and is blocking the exhaust?

I put the new PCV valve on the wrong valve cover so it ran with two PCV valves and an extreme amount of vacuum for a while, not sure if that messed something up.

Any ideas on what is causing the problems would be appreciated.

Thanks!
