O2 counts stay below 100

The main time it does this is at idle. It had gotten worse lately and now has a long delay after I punch it. I did a search and tried the cam sensor and tried to check fuel pressure but my gauge leaks. The sensor isn't too much more than a month old. I tried different chips as well. It will stay below 100, mostly at 000, until I give it some gas. Then it will slowly come up and act normal. While cruising, it is fine. When I let off during cruising, it goes back down to 0s again. Nothing but 93 gas has been used. This is really annoying since it seems to want to, and has, cut off at the light. I've watched my SM readings for all sensors and all seem fine except for the O2 readings. Any suggestions?

mine does the same thing at times but It does not cut off at lights.What do you mean your gauge leaks.do you mean it leaks down after you shut down or does not read accurate

I meant that I accidentally crushed the end that screws onto the fuel rail while trying to adjust it once. I got it back as straight as I could but you can never get it back round again. Therefore, it leaks. I bought a new adaptor from advance auto that I'm getting ready to put on. Also forgot to mention, new MAF, injectors have a few thousand miles, and it's a new fuel pump. It mainly does this when I'm not giving it any throttle. Anyone else have this problem, and how did you fix it? I do remember the other sensors doing this too. It happened one night after I went to the track and started blowing fusible links. I thought it was normal.

What are your blm and int while this is happening?
You might want to look for a vacuum leak.
