i had a similar problem and i had to use my laptop to connect to my truck to read the sensor activity, for me it was the cat. my sensors worked except when in the bank behind the bad cat.

how did you connected your laptop to your truck and do you need some special program or cable???????? Interesting

If you have a four sensor set up.. 2 before cat two after.. The two before cat tell computer to run the motor air/fuel mixture.. Two after cat had to have different reading bc the exhaust has to be changed in the cat.. If it's the two after cat sounds like the cats are bad.. One fix is o2 sensor simulators.. 42 bucks a piece.. They plug into factory plug an zip tie up in your harness.. Afterthoughtsauto.com they tell the computer what it wants to hear..
