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.

POST 1 / ORIGINAL POSTEROriginal post

Even before I had my motor rebuilt, my car's CEL was coding 1128 & 1130. After changing the right side O2 sensors (because all the coolant killed them), I still have the CEL. Uggh. I have not been able to find much Porsche specific data for an OBDII reader. Any ideas what I'm up against THIS TIME? FYI, my entire top end had to be transferred to the new motor because of the E-gas difference in the 1999 C4. Maybe this is a MAF sensor since I kept the same throttle body? Please help - I just want it gone. Joe
