Typical remix low idle rough running troubles.
A weird problem I found out with my O2 sensor. Unplugged it runs the same, removing the relay it runs the same. The odd part is using a multimeter I can tell it gets good power on 30. The ground is good. And even gets a clean signal to turn off and on. The weird part is on 87 I am reading a voltage with no relay. 87 is the relay output and goes straight to the sensor. With key in off position I get 0V. With key in run it shows 10.5-11V. With truck running it goes up to 12 while the battery sits at 14.4V. I have wiggled all the wires and there is no change at all.
So guys and gals, is this a case of wire harness teardown and trace the wires?
The O2 sensor is brand new. Like just a day old. I have purchased a MT2500 so I hope I can trace down any other troubles or bad sensors if possible. Hope ya'll have any insight to my woes.
Thanks,
Lance
