Alright, for those of you who don't know, my car is satan. While installing downpipes, I was forced to cut an O2 sensor wire in order to remove the old cats. I then removed the O2 from the stock cat using a crowbar (yes, it was on there tight) After getting the downpipes and test pipes on, i stowed the other post precat O2 sensor and left the wires on the drivers side one exposed (wrapped in tape). Well, today, i decided to splice it back together. After I spliced it back together, this whole mess of limp mode came on. thinking it was reversable, i removed the O2 again thinking I messed up the splice. After resetting the ECU, the codes came back almost immediately. I am thinking i shorted out my 02 sensors in some way, any idea of where I can locate this system or if I can isolate this and repair it myself, as I hate going to the dealer. Any helpful suggestions would be much appreciated. For those who dont know, here are all the codes i threw. Thanks for your input!!

I had one of those downpipe days as well. My advice: get bandaids, a beer, and a hot shower. You'll feel better
