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.

I have never actually met anyone with a Porsche who cleaned their K&N filter because it legitimately needed it.

He thought he may have gotten oil on the MAF sensor, so he bought cleaner and cleaned the sensor. No change in the rough running.

Suggestion

I would also go with a new filter (probably one of the new oilless ones...), and I'd use a filter sock to filter out the bigger particles that make the filter LOOK like it needs cleaning.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

All, I'm hoping to help a good friend with an 03 Boxster S. The car has a KN intake kit. He recently cleaned and re-oiled the filter and now it is running rough below 2,000 rpm. He thought he may have gotten oil on the MAF sensor, so he bought cleaner and cleaned the sensor. No change in the rough running. I believe he know has a CEL. I have no equipment to read codes. If anyone has any suggestions please let me know. Thanks

POST 2Original post

This is usually the MAF, try cleaning again or possibly a new one!

POST 4Original post

You can get relativity inexpensive videos readers I thing a member on here has a new Bosch unit that works well from what I've seen. Best to avoid reusable filters and stick to a paper medium.

POST 5Original post

if too much oil, clean the filter again, wash it , let it dry a day or so, and oil it a whole lot less. It needs hardly any oil, just a sheen. I use Pam veg oil.

POST 7Original post

"Cleaned and re-oiled the filter" is the answer to your question. Did your friend really need to clean and oil the filter? K&N recommends a 100,000 mile interval for their cone filters, 50,000 for airbox replacement (drop-in) filters. I have never actually met anyone with a Porsche who cleaned their K&N filter because it legitimately needed it. He'll need a new MAF - getting them working properly after over-oiling is a crapshoot. I would also go with a new filter (probably one of the new oilless ones...), and I'd use a filter sock to filter out the bigger particles that make the filter LOOK like it needs cleaning. Filter sock:

POST 8 / ORIGINAL POSTEROriginal post

5chn3ll, I'm not sure why he felt he needed to clean and re-oil the filter. Seemed like a dumb idea to me also. Unfortunately he did it before he talked to me. Thanks all for the advise.

POST 9Original post

What others said, sounds like MAF. Should also suggest he swap it out for an OEM airbox.
