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.

Suggestion
Check the insulation on the coil packs too, as that is a more common cause of misfires than the plugs themselves.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Does anyone know how to replace spark plugs on a 996 please and how easy is it? The engine sounds like it's misfiring and the Emission Control Warning Light has now come on. I was informed at last week's free clinic at JCT 600 in Sheffield that there was a slight leak on the spark plug covers and could cause eventual misfiring. John

POST 2Original post

Hi I don't know about slight leak on spark covers! but there are often cracks in the coil packs 1 on top of each plug, you can see the cracks and the coils swell up! Replace the cracked coils or all of them, easy to do from under the car, take the coils out and then you can get to the plugs. Berny.

POST 3Original post

Here you go. Check the insulation on the coil packs too, as that is a more common cause of misfires than the plugs themselves.

POST 4 / ORIGINAL POSTEROriginal post

Thanks for that Richard. As always, you're a life saver. I don't suppose these are available in the high street - Halfords perhaps. Or can you only purchase them from a specialist. otherwise I'm grounded again this weekend. John

POST 5Original post

Most specialists have them in stock, as they fail so often. If you have a Euro Car Parts local, they should have them too.

POST 6 / ORIGINAL POSTEROriginal post

Well, I cheated and took it into my local Indie. They diagnosed a burnt out coil which they promptly replaced (10mins). I was also informed that the others had cracks on them so will need replacing at some point. Don't know whether to wait until next service in June(ish) or do it myself at a huge saving (in money not in time) Thanks all. John
