133 is bank 1, sensor 1 slow response. 144 is high voltage bank 1, sensor 3 which doesn't make sense - sure that's the right code?

134 is insufficient switching, bank 1 sensor 1. If that's the code they both point to the drivers side precat sensor.

ok went to auto zone and they said it shows P0133 & P0134 (both as pending) and shows P0153 ?
Those are the only 3 codes I have now vs the 11 I had like 2 weeks ago :/ So should I just get my comp tuned and see if that fixes it or should I do something else first (if something else can you let me know what, as in to fix the codes) thanks.SLP lid, SLP CAI, K&N air filter, Ac Delco Iridium plugs, Gutted Cats, QTP 3'', TB Bypass, LT headers w/ORY,

P0153 is slow response, bank 2 sensor 1. You can look up the individual codes for your year at gearchatter.com, assumes your stock but might find something. Someone will chime in now that the codes are verified.
