Cant find any links so here goes. 3 times in 500 miles of street driving, I have made a left turn and when I get back on the throttle, the engine is dead for a second. It seems like the 1/2 tank of fuel all goes to one side and sucks air. Twice was just at an intersection and once at a traffic circle.(All were aggressive corners) Once I was in a higher gear than I thought but the other two times was totally normal driving. Pressing the accelerator just does nothing, Lift and get back on it and things are normal. Since I cant duplicate it, that's about all I can say. Fuel tank was at 1/2 all three occasions, reads accurately and will run fine to 1 bar. No other starting, running or CEL's issues. Bone stock engine . 87,000 miles.
Any ideas besides wait for it to get worse so I can diagnose the issue?

 

Clean your IAC Valve. This should fix your problem Dave

 

Seems easy enough to try.

 

Im genuinely curious here. How would the idle air control valve have any affect on power delivery while taking a corner in gear?

 

This follow up is too early to say anything for sure but here are my thoughts so far.
When I removed the IAC, it was very clean in my view but I did the brake clean, WD40 and compressed air suggestions and removed a small amount of "carbon dust".
Made sure the little internal cylinder could freely turn within the body. I also removed the PCV and cleaned with brake clean and air. Removed the Map Sensor and decided there was nothing to clean and reinstalled it.
The car ran fine before so there was not a night and day difference but after driving it a couple days, I have noticed a couple of things missing.
At cruising speeds, I had an occasional throttle tip in whistle which seems to be gone.
I also had a clutch buzz that got worse the last few months and learned how to avoid those RPMS. The clutch buzz is gone. (Was the air being totally cut off and it was acting as a Jac Brake or running rough causing something to vibrate? )
I also had the occasional shutter symptom coming to a stop and I suspect that is gone too which makes sense since cleaning the IAC is the suggestion for that problem.

Will it cut out going around a corner still, I have no idea but I sure like the "normal sounds" that went away so far.
