I tried tuning the car a bit this afternoon using my palm and the safc but the fuel trims don't seem to move.

My low is stuck at 102% which seems to good to be true. I even trying playing with the safc to add and take away fuel and they still don't move.

Any ideas????

I also noticed last night that the o2 voltage doesn't move and the feedback trim is stuck at an even 100%.

This sounds like a dead o2 sensor to me.
WHat do you guys think?

Fixed it.
