Engine Hesitation

[David4315]

So I'm driving back from a Cars and Coffee event this morning and in 4 gear at about 50 MPH I can feel the power coming on and off like there is water in the fuel or something. Pulling into traffic a couple of times recently I've nearly stalled and just thought it might be operator error. But in fact it would seem there is some sort of issue with the car and not my clutch foot. I'm not sure if this is a common issue as this is my first Porsche. Any wisdom from the list is as always appreciated . Still under warranty so I'm not too worried but always disturbing. My only real concern is that I installed the AWE exhaust and there could be an issue with the oxygen sensor which would not be covered . Again thanks to anyone who might have more of an idea than I do.

I think you start by reading the fault codes.

I had the same issues this weekend for the 4th time. It fixed it 's self and no fault codes where to be found by my shop. The did reinstall the software and it runs better now that before the incident. I wish somone would/could fine the cause if this issue as it has been reported for years.....GR
