Hey guys. I’m having a really weird issue with my Infiniti. I was driving on the highway maybe at like 3,000 rpm. There was traffic buildup so I had to hit the brakes kind of hard. As soon as I did this, the rpm jumped 4,000 and made a revving sound. It has done it a couple times over this weekend . Only when I’m braking light or hard. Any ideas what it could be?

I also have these codes
