I just went over to my friends house and helped him convert his 7wire o2 setup off of his VX harness to a 4wire did everything right and is still throwing a code and is still running rich, does ay body know how to solve this?

Your out of luck buddy. Sorry to tell you

 

Maybe those connectors we used on the o2 arnt getting continuity. Just maybe, those connectors didn't work at all... Just a thought.

 

then how did the a/f read when we started the car up?

 

i can bring my volt meter over and we can check the continuity on it, but i don't think that it, if the a/f is reading then the o2 has to be gettin power on it then.....

 

if you are getting codes you need to trace eahc wire and test to make sur eyou got good connections and the right pinouts etc...

 

REmember signal wire off the O2 sensor is shielded, it's sensitive to RF interferance.

Check your splices, I used blade connectors in the passenger kickpanel, and had to swap them with butt connectors, fixed some of my codes.

what is a blade connector?

aka "spade" connector

...replied to H-T post.

Posted the wiring connections on H-T. It has to be the connectors b/c im sure the wiring is correct. Also, re-read this thread. He said because the a/f gauge was getting a reading. Not really. When car is on, the gauge would show half the led spectrum in a fading manner. If I hit the gas, all would get brighter but wouldn't move in an individual led. Get what im saying? It's like its not getting a strong enough reading. ( connection problem maybe?)

Ugh
