My girlfriend has a Plymouth Neon DOHC and I've been at the exhaust for a few days now. How hard is it to replace the oxygen sensor on the catalytic converter (downstream sensor I think it's called) since the original is very hard to unbolt and I noticed one of the four wires has come off (grey wire) if that has some significance. I've seen the exact-fit replacements so where does the opposite end plug into?
I have the end I am talking about circled in red.
have the same problem?
