Ok, this thing is getting on my nerves. I had my check engine light on and it was because of my #2 O2 Sensor. I rigged it with a spark plug fouler from autozone and it worked. Then I had to rebuild my motor from melted pistons a month ago. Now I drive around for 3 miles, 15 miles, or 40 miles and sometimes the check light comes on and other times it doesn't. Its throwing a code 1 which is the #1 O2 Sensor. I rigged that one the same way as the #2 and it didn't work. I'm still getting the light. I took it to Autozone and they tested it (code 1 again) but they said it was too much voltage.....is that a bad O2 sensor or maybe just a wire ( I have one taped off from a air fuel gauge)?

 

anyone?

 

?

 

i would check the connections at the wires and the a/f guage wiring...

 

I'm sort of hoping that's all it is.
