If it's still evident once warm, I'd do as JFP recommends - check the engine / tranny mounts.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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

Have a 2007 997 non turbo 3.6 manual transmission Porsche with a 9222 km. It has a strange vibration from almost idle and up to 2.5 k RPM. Have check for spark plugs, coils and have also cleaned fuel injectors. No codes so far but still vibration exist. May it has something to do with clutch? Or any other idea on what to check for? Regards Ray

POST 2Original post

When hot or cold? 996/997 can be a little 'lumpy' until warmed up some, assume it's the auto choke.

Check you engine and transmission mounts.

So far I have notice it either cold and hot.

At naked eye all them seems to be 100% ok. Vehicle feels pretty much like a misfiring (kind off) at the beginning and mid range. Also have noticed traction control time to time for blinking with no apparent reason at all....

If it's still evident once warm, I'd do as JFP recommends - check the engine / tranny mounts.
