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.

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

0 evidence records excluded for query context · 1 excluded by outcome qualification · 0 adjusted by outcome qualification.

POST 1Original post

Car was parked for two days. started this morning got check engine light. checked with OBDII scanner and i get code P0301. any suggestion? can it be from exhaust . i recently installed a B&B (billy Boat) Exhaust also IPD Competition Plenum, 06 Cayman S

POST 2Original post

P0301 is cylinder 1 misfire, passenger side front. Maybe a cable connector was dislodged in installing the exhaust . Or maybe happenstance. I'd check and see that nothing was pulled loose though if the exhaust is cat back you really weren't close to these cables. Otherwise if it is running ok you could clear it and see if it returns. Ghost in the machine and all that. I wouldn't expect a misfire on only one cylinder from what you've done other than coincidentally loosening a coil wire etc. Maybe you already know but if you just google the code you get the basics right off. What the code is and possible causes.

POST 3Original post

Thanks for the reply. Exhaust and plenum was changed over a month ago. car has 39K on it. not sure if i should just change the spark plugs and coils. i cleared the code i'm going to drive around the block to see if i will get it

POST 4Original post

Think plugs were recommended at 4 yrs or something like 40 or 48k miles so you could be due. I've seen a mention or two of cracked coils too. Going for a drive is a good plan. I've had codes just appear and never come back before so good luck. Wish it was warm enough here for a drive.

POST 5Original post

Cleared the code. After driving 150 miles got the same code. Just going to order the coils and change them.

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