Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

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.

2 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.

POST 1 / ORIGINAL POSTEROriginal post

Scanned a 1999 C4 today (for sale) with Durametric pro. Car has 74,000miles. Ambient temp 0*C/32*F. Bank one read 80 degrees at rest/cold, bank two at zero (0). Readings at idle cold, unchanged. Readings cold at 3000 rpm bounced to 107 degrees bank one, 0 degrees bank two. Readings with engine warm were the same/unchanged. Returned to 80*/0* at idle/warm. Car has, according to receipts from seller and reinforced by Original two row IMSB "in-hand" (perfect btw), a new "FVD" IMSB installed within the last 2500 miles. Also has an evoms Tune dating back to 2008. Approx 20k ago. No check engine light. Car runs strong. Only codes are 1130 and 1137. Thoughts?

So, let me get this straight ... you scanned a 1999 model 996 and you're getting O2 sensor faults? You're getting those faults, but no CEL on the display? Weird. I would move on to the next one, especially with that FVD bearing in the car. I wouldn't trust it.
