4.0 SOHC throwing 7 codes!
 

My fathers gf has a 1997 2wd ranger with a 4.0L SOHC. The thing would run great until it warmed up. After it warmed up and went to stop at a light, it would have a lopy idle and stall, yet if I put it up into nuetral at a light, it would idle just fine. Went to the auto parts store and had them read the codes and this is what I came up with:

Anyone have a listing of what these codes mean?

P1443
P1151
P0153- bank 2 sensor ckt slow response
P0401- EGR flow insufficient
P0171- Too lean bank 1
P0174- Too lean bank 2
P0420- Catalyst below threshold

Is there any way that a clogged catalytic converter could be throwing ALL of these codes?
