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.

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

Yes it going for a scan on Saturday so helpfully it will show the fault code ??

POST 7Original post

With an EML, even a £16 cheap OBD2 reader will tell you the issue. Buy one from Amazon, Euro Car Parts etc. They're usually good enough to even tell you the cylinder not firing properly, should it be plug, coil or fuel related.
