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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hi everyone, I'm experiencing a rough idle on my boxster. I hooked up the Durametric and I have the following codes: P code 174 P code 62 P code 65 cyl 3 misfire P code 63 cyl 1 misfire P code 64 cyl 2 misfire. I had a misfire on a single cylinder a year or more ago and it was a hairline crack in a coil-pack. Any ideas what would cause 3 cyl. to miss all at once? I only replaced the 2 worse coil-packs last time. But its been running great until recently. I replaced the CPS which cured my hot-starting issues. The roughness seems to smooth out with increased rpm's although Its probably just less noticeable. Any input greatly appreciated. Thanks, Garry

POST 2Original post

I'm no expert but I had misfire on 4, and it was my AOS that had failed

POST 3 / ORIGINAL POSTEROriginal post

Hmm. I replaced my AOS about 2 years ago, but I'll check hoses to and from. Thanks, Garry
