I finally got my car working again but of course the boost controller doesnt work...I have to send it back to greddy to be looked at and fixed hopfully!! Anyways, I took my car out for a run today and noticed that my air/fuel gauge isnt operating as it use to. It doesnt bounce back and forth like it normally does and it also doesnt go rich when i floor it. It stays at stoich. it does go completely lean when i let my foot off the gas though. could these be signs of faulty o2 sensor??? i have no signs of detonation and the car runs better than it ever has. i just fixed an exhaust leak so i think that while i had the exhaust leak my ecu was dumping fuel and killed the o2?? what do you guys think???? Thx!! *note* AFC broke so i dont have a voltage reading on o2 =< [br />

hey man, my A/F gauge was doing the exact same thing here lately, turns out my ground had worked its way loose a little. i re-ground it, and no more problems.

I'd swap out the o2 sensor just to be safe. When that thing goes out their is no way your going to go anywhere far. Better safe than sorry and you will get better readings than an old one.

Just my opinion, I will be changing mine soon too.
