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.

POST 1 / ORIGINAL POSTEROriginal post

Just changed spark plugs on my 996. After much swearing and extreme body contortions, only to find engine runs rough and check engine light pops up to confirm something is amiss. I think that the problem lies with the coils. Either there is a connection problem with the clips, or one or more of the coils is faulty. I plan to recheck connections, or is installing a new coil pack recommended? Thanks

POST 2Original post

Check the plugs where the harness plugs into the coils, one or more are not seated.

POST 3Original post

If you have an OBD reader or Durametric, you may be able to shorten the search for which position it is, by learning the "Pxxxx" misfire code.

POST 4Original post

Did you check if the coil packs were cracked? This is very common. When you removed the coils you may have sent them to the grave.

POST 5 / ORIGINAL POSTEROriginal post

Thanks for your response. I rechecked the coils and found one that was not connected, as the rubber boot was folding under. All is well.
