Okay my pass 02 has been reading funny so i go to check it out and i can see it got burned on my headers. Not completly just burned the rubber off. Its in the area between the headers and fender well. So anyway i pull out the 02 harness from up top and i cut what is burned. I solder it back together and put some of that heat shrink stuff on it(lil rubber tubes). I know for a fact i did not get any wires mixed. I did them one by one. Now my 02 is only reading 003. Before this it read around .100 to 200millivolts. oh this is the wire comeing out the PCM. I also sprayed electrical cleaner from NAPA on the wires i cut and on the connectors. This is everything i did. Anyone have an idea of wat could be wrong? Did the wires that were burned touching each other short out the O2??

 

you should be able to read the resistance of the o2 sensor with a meter. The spec should be in a chilton I believe......

 

I thought I read here before that you aren't supposed to solder the o2 wires because that will through of the resistance readings or something like that.

 

I thought that was for only the wire coming out the 02 sensor, not the wire coming out the pcm. Hmmm ill maybe go back in there and take all the solder off and see wat happens.
