Why does engine rev up and down when I step on brake?
My engine isn't missing at idle or acceleration. When I step on the brake it revs up and down as if it is going to stop, but it doesn't. I let off the brake it revs/runs fine...

I have the same problem it's a leak in the break booster so when u hit the breaks it's letting extra air into the engine and therefore revving check for a suction,vacuum sound right behind the break pedal when braking it shouldn't be there. If this all matches replace your break booster

I have the same problem but I was also wondering if when it revs it wastes more gas, so I could replace asap. (It’s been using more gas than usual)

I am a mechanic and the most common problem to agree with the above comment it is a brake booster
