Question about o2 wiring... Ok I'm having some issues with a new motor I just dropped in. It is absolutely dumping to much fuel. Here is the question:
1) Should the wire going to the connector for the o2 sensor be hot (contain current) when only the key is turned forward?
Basically I used a test light all over the car and just about everything is on except when I unplug the o2 sensor and put the test light on the connector it is containing no voltage and is not hot. I haven't crawled under the car while it runs to check for voltage yet. I was told that it should be a hot wire when the key is turned forward. Here is my other question:
2) Where do the o2's ground at?
Thanks in advance for any help...
