got these 6 codes when i gutted my cats... my question is, if i get some 02 sims, will those delete the codes? if i get a Predator Programmer to delete the codes, will it get rid of my SES light??

All of these codes deal with bank 1, so they are most likely related.

P0135 and P1133 refer to the first oxygen sensor, so it sounds like it is bad and needs to be replaced. P0171 means bank 1 is lean...bet if the 02 was replaced all three codes would clear up.

just to clarify, p0135 and p0161 refer to my rear 02's right? and the p1133 is referring to my front driver's side 02 which needs to be replaced? if get the rear 02's tuned out, can i reuse them on my front driver's side 02 instead of buying a new one??

guys...he said he just gutted his cats. of course he is going to get codes. you'll have to get a custom tune to delete the codes.

P0161 is for the rear. The others are for the front 02's. P1133 is insufficient switching for the front 02 (i.e. it is not reading fast enough). P0135 is front sensor heater malfunction.

You need to replace bank 1 sensor 1, and have the rear o2's turned off. You can use a rear 02 in a front 02 so long as its good, and after gutting cats and running it there's no guarantee that both rear sensors haven't been fouled out.

No kidding but half of the codes he posted are for sensor 1, which is in front of the cat.
