: Need Some Heil with 2000 STS

Hi guys, I have a 2000 STS acting up . The O2 sensor Bank 1 sensor 2 is coming up all the time. Replaced it twice to no avail and then swapped it out with bank 1 sensor 1 and still showed up as sensor 2. Check wire and seems to be ok. Also am having trouble with fuel gauge swinging from full to empty and anywhere in-between ay any random time of operation on the road or standing at idle. Looked at PCM connection and this seems to be ok. Any help would be appreciated, thanks Dave

Please post in the Seville forum, this section is for the 05+ sigma based STS, totally different animal.
