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.

Suspected cause
It has 120K miles so I suspect the ignition coils are starting to go.

Suggestion
When Ford had the 4/4 split coils on the 5.0 V8 changing four always caused a problem; that was told to me by a professional wrench with more than 46 years in his shop.

I strongly advise replacing them as a set, individual coil changes have often been a problem I was informed about by professional mechanics.

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 1Original post

Hi All, Hoping for a bit of confirmation. I've picked up a 2011 Cayman 2.9L . Beautiful car and love it to bits. It is however a little bit poorly. The car has a misfire on Cylinder 2. Only happens after the car is warm and has been left to sit for a few minutes. It has 120K miles so I suspect the ignition coils are starting to go. Well I hope so! Planning on getting it jacked up in a couple days once a replacement coil has arrived (Yes I will replace the other 5 if the issue is resolved). I just wanted confirmation on which side I should be working on. I'm based in the UK but from what I've seen online and researched, if I'm facing the rear of the car, I should be removing the right wheel (Drivers side UK)? With the second cylinder being in the middle. Thanks .

POST 2Original post

Assuming you are standing behind the car, that's correct. Bank 1 is on the right side. Plug 1 is at the front of the engine. We need to use caution when searching for Porsche info online since the 911 mounts the engine backwards.

POST 3Original post

Thank you for confirming, the 911 being 180 degrees is exactly why I needed to ask haha. Despite all the manuals I have for this car. I couldn't find any info about the banks!

POST 4Original post

I knew I had saved this image that I grabbed from somewhere. It should apply to all Porsche flat 6 engines. Just note the orientation of the belt driven accessories to determine the front of the engine.

POST 5Original post

I strongly advise replacing them as a set, individual coil changes have often been a problem I was informed about by professional mechanics. When Ford had the 4/4 split coils on the 5.0 V8 changing four always caused a problem; that was told to me by a professional wrench with more than 46 years in his shop. You’re getting free labor and in case they are old? Do all of them preventively, it’s a bit of a trip to get there anyhow. I’d do the plugs too to be honest, good luck.

POST 6Original post

That’s my plan. The car is booked in for its service in 2 weeks. Ideally I need to be able to have it make the 45 minute journey. Hence the 1 replacement. I’m capable of replacing the one coil. I’ll have the professionals do the plugs and the other 5.
