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.

Outcome without a verified action link

I'd say tightening fixed it.

POST 1 / ORIGINAL POSTEROriginal post

I put equal length headers on and they are great. I makes everything feel more smooth. I've gotten P2098 twice in the last 700 miles. It doesn't seem to affect anything. I just clear it and go on. I also have muffler bypass pipes. Any idea what it could be?

POST 2Original post

POST 4 / ORIGINAL POSTEROriginal post

They are brandless, but seem very well made to me. Does the car just have to adjust to the new flow?

POST 6 / ORIGINAL POSTEROriginal post

I checked and had one bolt with space between the header and the bolt head. I tightened it all the way so hopefully that was it. It was on the left side. Can my code be narrowed down to which side had the problem?

POST 8 / ORIGINAL POSTEROriginal post

I'd say tightening fixed it. Thanks!
