Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.
0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.
0 acknowledgements have no verified action link; they do not establish a repair result.

getting CEL warnings after recently fitting new O2 sensors and Eurocup GT cats so Im thinking I need to fit some extenders to the sensors. Do I need to fit extenders to all 4 sensors or only the two post cat sensors?:
Just the post two cat sensors. I bought mine from pep boys. they're the 18mm ones and I think its was less then $5 for the pair.
thanks
They're actually called spark plug anti-fouler. If you go in there and ask for a sensor extender they will just stare at you with a stupid face and ask you ten million questions as what you actually want to do and why.
This is a source reference. Confirm exact model applicability in the original material.
