Running Rich?? long tubes no cats, mods in sig, seems to be blowing black smoke out of tail pipes during WOT runs. Popped a couple of codes for bank 2 sensor 1 O2 now it seems like I have a dead cylinder? I was thinking that I could have fouled a couple of spark plugs but I am not sure and have yet to pull a plug. Is black smoke normal for uncatted cars or am I in fact running pig rich??

Yeah definately new plugs and 02s, sadly that set of TR55 iridiums that are all fouled up now only had 1k on them but whatever. I started pulling plugs today to see what was going on and bank 1 looked GREAT...bank 2 not so much. I do have another question tho is Delphi made my AC Delco?? I found a great price on Delphi but wanted to make sure before I bought them.
