I've recently had some weird issue with my o2s. I installed LTs and a full exhaust 10k miles ago. Deleted rear o2s and got a tune. Everything was fine till a few days ago. It threw both p0153 and p0133 for both front o2s. I changed both sensors and cleared the codes. A few days later both codes came back. Why would it be doing this all of a sudden? Any thoughts?

you need vibrant o2 restrictor part #11619 install the smallest ring there 3 of theme, on my mach 1 i have bassani off road with mac cat back no cats and i pass etest and n codes.. good luck
If youre talking about the rears it doesnt have rears. The code is for circuit slow response but its affecting both sensors. If this means anything the code doesnt come on for a while 100+ miles
ya take a few mile before they work for some reason mine did the same i clear it then a week later the engine light would come back on.
so i put the vibrant been 2 month and pass a emission test like i add stock h-pipe with the cats..
its the front o2 you got to put the o2 restrictor

Did you check all the plugs? I know it sounds dumb but I had troubles with o2 sensors and it ended up being a pin in one of my o2 plugs. I was throwing P2195 and P0133. Here is a link to my troubles.
