Sometimes misfires

Sorry if I write something wrong this is not my first language.

my car is great in every way. No problems at all, but when I turn right and accelerate the car revs up but will not go forward for about one second or two and then goes again like nothing happens. It also does it when I am going slow and hit the accelerator hard. Other than that random thing it runs perfect. I tried very thing and I do know what it can be.
