What is this wire for? It's on the wiring harness side of the oxygen sensor clip. I just noticed it wrapped around the other three about a month ago, is it a ground? I changed the oxygen sensors about 3 years ago when I swapped the motor, but I don't remember romoving this from anywhere...
My car runs rough (doesn't idle well) for less then a minute after startup, and has done so for a long time. If this needs to be grounded somewhere, I'd like to do so.
Also, I have the Orange wire (associated with the O2 sensor system) grounded to the body of the car, is this incorrect?
It's been a long time since i've been active on this forum, but have recently done a lot of little maintenance and performance mods to my car... Good to be back.
