Went with a full Z06 exhaust conversion on my LS3 GS and these codes just popped up. I remember connecting all of the O2 sensors and tie-wrapping them out of harms way. Any ideas what could be causing the codes? I've already cleared them out once but they just came back.

I don't know so here's a bump... I will be doing this on my 07 ls2.

very common, happened to me, you nicked the wires for a vent valve thats back there, infont of the diff mounted to the bottom side of the trunk. it typically blows a fuse up front, which in the case of my manual also controls the reverse lock out function.

check for nicked wires and a blown fuse in the engine bay. i cant remember the number. possibley #14

No blown fuse, but I’ll have to crawl underneath and check for any nicked wires. Thanks for the heads up!
