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

Getting a very odd problem with my 996. At around 3,000 RPM when I'm accelerating I get a subtle drop in power. If folks know how it feels when an A/C system kicks in, it kinda feels like that. It's only for a moment but it is noticable and I'm not sure if it's affecting the overall performance of the car. If I accelerate hard, I don't notice it but I'm not sure if the car feels quite as quick as it should. Any comments? Migration info. Legacy thread was 77123

POST 2Original post

could be one of the leads breaking under load, or a duff spark plug again under load or possibly the MAF sensor, get it checked, however if it is intermitent, then best to leave untill it gets worse, which it will if it is any of the above. Could also be one of the injectors fouling, worth putting some injector cleaner in anyway Migration info. Legacy thread was 77129

iginition lead would be my guess Migration info. Legacy thread was 77132

POST 5 / ORIGINAL POSTEROriginal post

Thanks for the feedback. Taken in to OPC and the technician says everything is normal, no error codes from the engine so will just have to keep an eye on it. Will try some injector cleaner, any recommendations on a good one? Migration info. Legacy thread was 77624

POST 6Original post

A few tanks of Shell V Power or BP Ultimate should help. Perhaps worth getting it checked out on a rolling road, e.g West Tuning or somesuch. That will quickly show if the engine is performing as advertised. The 40th Anniversary cars should feel pretty sprightly, with a few useful extra hp over standard... I'd be wary of engine injector cleaner additive thingies that have not been recommended by Porsche GB. Migration info. Legacy thread was 78974
