Help! My first big problem with the evo. It's busted! I had just installed my Injen intake system with IC piping. Everything looked good. I have a Cobb TBE and a stage 2 ECU reflash using Cobb Tuning Accessport. I went to test drive just after the install. Started great. Felt like there was a little more power. With the Injen and the Cobb TBE, and the reflash, it was really opening up. When I got on the highway, I really hit it. It was going well and then "pop!, Swoosh!" car stops running. Well, I could keep it driving at about 5mph. If I tried to accelerate, it would putter and stall. From the sound, I thought maybe I blew off a hose or something, but I looked and it seems everythings still in place. I got a "service engine soon" light. The Cobb Accessport reads the codes and it told me that the code said "O2 sensor no activity" and it specified a certain area like "sector 1, panel 1" or something. DOES ANYONE KNOW WHAT WENT WRONG? WHAT NOW? Worst of all, my wife hates when I do anything to the evo, now she's gonna think I broke it! HELP.

Sounds like you blew off intercooler piping, but that wouldnt explain the code.

Do you have a wideband air/fuel ratio gauge?

That was the problem! The lower IC pipe did come disconnected from the IC. Had to pull the bumper again to find that out. Ugh. but, it's all good now. Thanks!
