Question about 2003 Oldsmobile Alero
No it's not hard but you need an 02 wrench and it cost 8 bucks, disconnect the wire harness and put the socket on and unscrew it and install the new one, there are two normally and you need to know if it's #1 or #2 if you have 3 you need to know if it's bank one or bank two or the rear 02 sensor that is after the cat but they all look the same.
