Hi everyone. Good to be back on this site after some time away.
I'm pretty sure I have a bad O2 sensor. I'm trying to figure out which one based of my VEC2 log. They are definatly different from each other...
As you can see, one is fairly flat at idle, and the other is very "jittery". I know stock O2 sensors are supposed to pulse back and forth several times per second, but i'm not sure how much.
By the way, this is to try to figure out why my '94 stalls during idle unless I give it some gas.
