Hi Guys, Could someone please tell me if their is a difference between up stream and down stream oxygen sensors? My "02" V8 only has up stream sensors which have a orange plug but when I ordered a replacement I received a grey plug which I have since read the grey one's are for downstream? Would this matter, is this just color coding or am I completely wrong here??!!
Cheers Ted.
