Pulled codes, kinda confused

[bigbird]

i bought a code reader and pulled my codes today. the car is currently surging under heavy throttle, but boost isnt beign effected. well im not sure these codes have anything to do with it(may be wrong though). they are as fallows
P0130- o2 circut malfunction (bank 1 sens. 1)
P0133- o2 sensor ckt slow response ( " )
P0150- o2 circut malfunction (bank 2 sens. 1)
P0153- o2 sensor ckt slow response ( " )
P0420- cat efficency below thresh (will this one cause the bad o2 codes?)

ive searched around and can only really find the info on teh codes but not what my next step is to fix it.

i would begin with bank 1 sensor 1 first, change that one, reset code, and drive for a week or two, see what else come back

my 97 camry i4 had P0171 and P1130, P1135,
i changed the A/F sensor, and the P0171 went away as well.

I agree. The P0420 is probably being thrown by the O2 sensor codes, not the other way around. I'd replace the first two O2 sensors, reset the code, and see what comes back.

If you're boosting, you may be running rich and fouling the O2s if they both went at the same time.
