Couple of questions

[desertspyder]

Well, I was getting ready to check out my fuel trims yesterday when I found that my o2 sensor#1 reads 0 and nothing else. I'm guessing it's dead but wonderng why I'm not getting a code from it? Plus the car runs fine. And could this be the reason for the almost stalling when my BOV pops?(I am recirculating by the way)

If your reading 0 on your o2 sensor it is most likely dead. Sometime's they won't throw a code if they are completely dead since they aren't misreading fuel trims. Check to make sure that the o2 sensor is plugged into the connected properly. Sounds like it might have gotten unplugged. Also did you use a scantool to check this or is your AFC not reading it. You could just not have it hooked up right either. Check the voltage at the plug with a voltmeter and see if it fluctuates. And if you are almost stalling when you blow off then you might have a nice boost leak contributing to that.

It is plugged in and I used one of those big scanners from our auto hobby shop. I don't have my AFC hooked up to the sensor because I read that it degrades the signal. The rear sensor fluctuates but the front one is just dead in the water. My fuel trims were reading 5.5 for short term and 0 for long term so they were pretty decent but I couldn't get them to change with AFC. I just did a leak test and there were no leaks except at my BISS but I fixed it. Could a leak at my recirc hose cause this? The clamps are very tight but you never know.

Could. I have seen the dump tube's crack when people are taking the recirc. hose on and off a lot.

My intake is metal and I'm recirculating a GreddyRS there are no cracks in either of those or in my tube. I'll just have to figure something out. Anyway, I'm thinking it could be related to my o2 sensor so I'll change it out and see what happens. Just one last question... Will an o2 sensor from a N/T 2g eclipse work in my car?
