1997 Plymouth Neon. My "check engine" light has been on for the past week. I took it to the dealer and they told me it was because of my "upstream oxygen sensor". What and where is this? Is it something I can change myself? Is this the same thing as the "oxygen sensor" in my exhaust manifold?
have the same problem?
