Suggestion · Original poster
The codes indicate that all four of my O2 sensors are bad, and that my car is running too lean (possibly MAF is also bad), which I find strange, although possible.

Coverage and how to read this overview
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.

Hey everyone,
Recently purchased a 99 , 996 Coupe , MT. It was a good price and I saw it had some codes. See below . So far I noticed that the oil filler pipe is cracked. Car isles fine, runs fine. Does about 16 mpg semi aggressive city driving. Any thoughts?
Do you have a check engine light on? It does not seem that you have one as it shows "no trouble codes are detected".....can't figure out what you are really posting.
Thank you, I guess I did a terrible job wording the question. The codes indicate that all four of my O2 sensors are bad, and that my car is running too lean (possibly MAF is also bad), which I find strange, although possible. I was wondering, given that I have a cracked oil filler tube, if that could explain the issue, or if they are completely unrelated.
Thanks!
Obviously you need to cure the crankcase vacuum leak from the cracked filler tube before you do anything else. Then reset codes and see what happens. One step at a time would be my advice.
I broke a plastic coolant line that's directly next to the altenator while removing the altenator (PN 996-106-226-52-M100). So watch out for that too! Pelican Parts sells a billet replacement if you do happen to bump into it...
Thank you! I actually read somewhere on the forums that over 90% of mechanics break it (possibly exaggerated) but I know that meant 100% chance (real number) that I would break it
. So I ordered it Tuesday, just waiting for it
