Put longtubes on and now the car is throwing codes P0131, P0135, P0174, and P0102 WTF is going on with my car. It's an 01 Z28 and i just put on LT headers on it and took it into town. When i got there all these codes popped up. Car runs rich according to the A/F gauge and runs bad at low rpms and starts to pick up after i get rpm high enough. Can running open headers....no y pipe just headers ruin an o2?

yeah i was on the way into town to get the y pipe put on and welded...i kinda figured i could run it like that for a bit.......i guess i figured wrong. I bought the vette o2 sensor (part # 13111) and im going to replace them both and see what happens.
