ever have to re-ground Oxygen sensors ?
Ever since I've had my code it's thrown intermittent O2 codes, such as lean bank 1/2 and the even better CE code that tells me they actually shut off. (can't remember the exact number) I thought it would just be a bad O2, but two sets later I'm pretty sure this isn't the case. So the fact that they're shutting off completely sometimes is leading me to believe that the ground is really really poor or my eek is going bad.
So I'm thinking about just running a new ground from both harnesses. Has anyone done this before? Obviously before I run the new grounds I'm gonna wanna check with a multimeter, but the idea of being under my car while it's running doesn't thrill me. Some one please help me out with some input/advice. Thanks.
