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

hello all hit a dirty pothole earlier and thought no damage had been done. after starting the car up again it sounded different. almost borderline like it was going to stall. now when driving -yellow emissions light is on 90% of the time and flashes (never goes off) - car sounds different - louder and more like a chugging train. - acceleration is jolty and alot less power is felt. lower gears its very very jolty and chuggy porsche 987.1 boxster i assume ive smacked some part of the exhaust system underneath and either a split / or a bolt has come lose maybe? any ideas? thanks

POST 2Original post

If an exhaust catalyst has shattered things will get a little pricey.

POST 3 / ORIGINAL POSTEROriginal post

update tested the car today light still on but the car feels a lot better, something still isn't right the only thing that has changed was the car was not used for 24 hours so "cold"

POST 6 / ORIGINAL POSTEROriginal post

DanoS4 said: coilpack? A faulty coil pack will generally have symptoms similar to a faulty spark plug. Some of the most common tell tale signs that a coil may be defective include: A rough idle - yes - revs are not sitting constant the needle is moving An unexplainably louder-than-usual engine yep . louder and different sound A noticeable lack of power - not always, but yes A significant drop in RPMs while accelerating for no apparent reason not noticed A blinking or intermittently activating check engine light yes, yellow emission light

POST 8Original post

Are there any emission sensors exposed under there anywhere on the exhaust?

POST 9 / ORIGINAL POSTEROriginal post
