Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

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 everyone, I recently purchased a 2003 boxster w/ 65k miles in very good condition. I noticed that the CEL comes on when the engine is pushed near redline. The code is cylinder 1 misfire. First thing I did was change the sparkplugs. Then I switched the ignition coil from cylinder 1 to cylinder 2. Still having the same problem. Any suggestions are appreciated

POST 2Original post

I've had a cylinder misfire code from a loose fuel injector wire. It didn't seem to be engine rev related for me, but you might want to check that connection.

POST 3 / ORIGINAL POSTEROriginal post

I'm not sure if that's what it is because it had happened one time in other cylinders as well. At one point in a long trip (after passing with a high RPM), I had multiple codes go off, for cylinders 1, 2 & 6. There is also a strange smell from the exhaust (smells kind of like brakes) which causes me to think it may be the cat converter. Any thoughts?
