Please check your fuel cap

While servicing the NSX, another owner visited me and asked about the fuel fume while doing sharp turning, like lots of 180deg turns on twisty mountain road with nearly full tank.
I have seen many NSX with loose fuel tank cap and it was the same for this owner.
At the petrol station, normally you are fine but if you are in a hurry or obstructed, there is a chance that you didn't lock the cap properly and driving your NSX with a partially loose fuel cap.
If it's too loose, it could affect the engine operation on DBW LEV models with sharp rpm drop when you disengage the CL just before the traffic light or on approach to roundabout.
With OBD2 production cars, certain models will trigger the CEL but I don't think that will be the case on NSX.
[Edit: Even with the loose cap, unfortunately, you can still close the filler lid so you won't notice it....]
