Testing lower o2 sensor

[digital]

The FSM says the resistance between the terminals +B and HT should be between 5.1 - 6.3 ohms at 68 degrees Fahrenheit...What about when the o2 sensor is well above 68 degrees when testing?

i dunno. if you got an O2 code, try cleaning it carefully. make sure the wires on the harness aint melted. if that fails. replace it. common preventative maintainence on ANY vehicle

Hey Wristpin, I just checked the codes, I don't have any (light continually flashes when the jumper is in).. Hmm...I'm trying to track down this problem I've had for a long time where I can hear the motor stumbling slightly at idle, but runs fine at higher rpm's...

what engine?
timing.
ignition problem somewhere.
vacuum leak.
pcv valve

Haven't checked the timing yet, what if the timing is good, what else might it be? I just installed new wires, cap, rotor and plugs..

I'll check the PCV valve too, thanks Wrist
