I logged my o2 sensor readings the other day, and was wondering if anyone could tell me, if they should be linear "flowing" or erratic ? Any help appreciated.

they will switch back and forth

My truck hiccups when I start it, sometimes when it downshifts on a hill, and sometimes sitting at a red light. It isn't really a backfire, more like a really bad miss. Would a bad sensor cause that? Can I tell if a o2 sensor is bad from a log?

I would check plugs, plug wires, clean your MAF sensor.... doesn't sound like an O2 sensor issue...

you'd generally get a code if an O2 sensor was failing.
