hesitation/rough running after right turns???
Can anyone help with ideas on what to look for here? I've been trying to sort out an issue with the 924S . It runs great for the most part but cuts out/hesitates/stumbles a lot when making right turns!!!
I attached fuel pressure gauge to rail with a hose long enough to see while driving and it maintains fuel good pressure at all times, even while stumbling. So, I don't think its a fuel thing. There is a SLIGHT delay in throttle response (maybe a slight hesitation) on initial throttle application and it also doesn't seem to rev up to redline. It doesn't really rev above 5500 rpm.
Is there some sort of electrical connection that could be getting broken on right turns? If so, what?
It seems to run well going in a straight line and on left turns. But, this car is neither a dragster nor NASCAR so I need it to make right turns.

No advice for you other than I am going through the same thing, only on left turns.
I suspect the wiring harness, either the connections to the speed/ref sensors or the injector harness.

I had that happen to me, only on right turns! The solution was to unplug and plug back in the AFM. Not saying it will work for you, but I would remove all connectors and clean with something like Deoxit.
