Well the other day I was travelling to my sisters college. I started doing a pull from 3rd. At the time I was running 15psi. I noticed right away that it didnt feel as fast, almost sluggish pull. I was disappointed. So I took a glance at my A/F guage and noticed it wasnt dead stoich like it usually is. Knowing that the guage isnt that accurate i just turned down the boost with my MBC mounted where the cigerette lighter is and continued driving. Next day, now on stock boost, im driving home and the PANIC LIGHT COMES ON. :-0!!!!!
Then my A/F guage SLAMS all teh way to rich. Car felt fine, didnt run any different so i just drove home. So for the past few days my A/F has been JUMPING all over the place and even has been lighting up the WHOLE guage at once.. It's very Odd. I checked the wiring for the guage, which is all fine and I checked the O2 sensor. It WAS just hanging in the engine bay until now when I have it zip-tied to the wastegate tube, thingie (metal tube). There looks to be a burn mark for sure and i can definitely see some wiring.
Think I have a BAD o2 sensor? Or is my A/F guage completely messed up.
Every now and then the guage will start reading normal like it did on the freeway last night, but most of the time it is SLAMMED all the way to rich and lights up the whole guage when the sensor warms up.
Alrite enough drunken ramble for one night. Any answers, let me know before i start buying new shit! thnx guys!

. It was grounding out on the metal of the engine with exposed wires from being burnt. I just threw my exhaust manifold back on with the o2 wire clips. had another o2 sensor lying around, threw it on, and it's all gravy. I'm looking to replace it now though because who knows how long that sensor has been going. I think it's due for a change. but anyways, thanks for the help though!
