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

Hello all. My mint condition 2000 Boxster S is having speratic idle issues, every now and the it seems to idle wonky, its really slight, but as we all know, generally only the primary driver can pick up on such nuances. Sometimes when coming to a stop, it can dip up and down by a couple of marks, then equalize. And other times you can feel it when starting to accelerate. Any ideas or suggestions as to where I can start to look. The coils " look ok" Any fuel additive recommended? Puzzled!! Thanks in advance

POST 2Original post

So lets start with it is a 24ish year old car at best. Maintenance history? Porsche specific diagnostic tools available (PIWIS, PST2, Durametric, ?)? Last time the intake and throttle body were cleaned and how? How old are the MAF and O2 sensors? Looked at the condition of the plugs? Ever used injector cleaner? How old is the fuel? Octane high enough? Are all the hoses good? AOS age? Just random thoughts...

POST 3Original post

Also, is it a manual or tiptronic? Many possibilities as Mike noted.

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