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.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi Everyone, I have noticed that whilst my 98 996 C4 usually idles at about 850rpm sometimes it sits there idling at 1100 rpm. Is this correct and if not what is likely to be the problem? Many thanks, Brian

POST 2Original post

The tickover speed should be 700rpm. It sounds to me like you might have an air leak somewhere. A diagnostic check would be a good place to start to see if there are any error codes stored.

POST 3Original post

Faulty O2 sensor(s) will also cause these symptoms to happen, and the tickover will often jump up and down between these speeds - a quick diagnostic will let you know if this is the problem.

POST 5 / ORIGINAL POSTEROriginal post

Thanks Guys, Apologies for the delay in responding. I will mention this to the OPC when I next take it in (I presume these things will be covered by the extended warranty?). I'm based around Gloucester so if not I will happily come to Bromsgrove! Brian
