Re: Mustang Sounds Like Its About To Die
All 4 O2 sensors screw onto the pipe. Purple sounds like it is the rear O2, not the front though. But the colors could be different...
You can get replacement O2's direct from ford or you could get them from any autozone, oreilly's, advanced autoparts, napa, etc. Replace both of the front ones when you do it though...don't just replace one.
