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.

POST 1 / ORIGINAL POSTEROriginal post

My '99 boxster under 4k in warm weather (> 70 f) surges and boggs. If the temperature is cool outside the problem is not noticeable. Could it be fuel mixture? Accelerating in 1st & 2nd there's a noticeable acceleration and bogging spots between 1.5 and 4k rpm. It's really noticeable when it's really hot out. Rather than a linear power acceleration, there's areas in the RPM range when it feels like it looses power only to have drastically more power at 500 rpm faster then another 500 rpm it has a low power zone. I know this isn't much to go on, but not sure how to explain it better. Any ideas? Thanks!

Disconnect or clean MAF. Then see if any change.

POST 3 / ORIGINAL POSTEROriginal post

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