O2 sensor testing?
I have a strong suspicion my O2's are bad. (car running wayyy rich, changed and checked everything else, fuel press 40 psi, injectors are good, grounded, no leaks.)
I don't want to sound cheap, but O2's are $40 a pop. Also, I am anal. How do I check these? I am guessing something to do with resistance on one of the wires. I looked for values in my reference books but couldn't find any. Also, check engine light is disabled. Thanks in advance...
