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

Hello all, I’m going crazy over this P1328 code on my 2002 996 Targa manual. The car drives great with no noticeable issues, but I keep getting a check engine light. Here's what I’ve tried so far: Car has 156K miles and the IMS has been done by LN Engineering. Parts replaced/inspected : Camshaft position sensor MAS sensor Unplugged and cleaned both engine wiring harnesses by the passenger side (used electrical cleaner) Checked the VVT solenoid and cleaned the plug The oil was changed 4K miles ago and looks clean, although I plan to do another oil change soon. Has anyone experienced this issue or have any suggestions on how to fix it? Your help would be much appreciated! Oil looks clean not bad, changed 4K miles ago, I will be doing an oil change soon. Anyone ran into this kind of problem or can recommend a solution? your help is much appreciated
