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
Hi Jammy, I change a lot of dualmass flywheels on 987 range,due to vibration, with car stationary and take revs up slowly and i can feel the out of balance between 1000-1300 rpm, then it gets less.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hi All My 987.2 Cayman S with 46,000 miles is exhibiting some undesirable symptoms. It appears a little rough and uneven at idle, think American muscle car, with vibration and a little shake. It shakes when shutting the engine down too. When accelerating there's an initial lurch and then it's fine. Coasting in gear down hill it will buck and shunt a little too. The engine and transmission oil has been changed, air and oil filters remewed, plugs changed, checked the coils, MAF cleaned, throttle body cleaned and a high strength fuel cleaner purged through. That little lot doesn't seem to have made much difference. I do have duramatric and no codes are being thrown but a few misfires do appear, nothing that throws a CEL up though. So, anyone noticed similar symptoms? Any improvements after engine/transmission mount replacement? Are mounts covered under warranty? Any help appreciated.

That, or gearbox mounts. I would have thought they are warrenty items.

Hi Jammy, I change a lot of dualmass flywheels on 987 range,due to vibration, with car stationary and take revs up slowly and i can feel the out of balance between 1000-1300 rpm, then it gets less. I did have one with a seized dual mass,and the inside mirror was jumping all over the place,this will eventually cause the crankshaft to snap.I have heard of a couple that went. Chris

POST 4 / ORIGINAL POSTEROriginal post

Thanks for the responses. Hopefully it's the mounts rather than the flywheel. The clutch seems fine. I'll see if my OPC diagnose anything, seems that unless codes are thrown that not much gets done though.

This is a source reference. Confirm exact model applicability in the original material.
