My car is a 2005 997 3.6.
Recently it has developed an intermittent and dramatic loss of power at 2.5k rpm. This can happen in any gear and whether the car is not or cold. It literally feels like your foot has slipped off the accelerator. Ease the throttle for a moment and it goes.
This is really frustrating as it usually happens when exiting roundabouts. Less than ideal.
The car has been into a Porsche indy who struggled to replicate the issue and couldn't find any evidences from interrogating the ECU. They could only find some very minor missfiring which was not serious enough to throw a warning light but pointed at the original coil packs being past their prime. These have been replaced along with plugs etc.
The power loss definitely doesn't feel like a minor missfiring, so what else could it be? Throttle position sensor etc.
