Anyone know what's wrong with my car?

I have a problem with my 2000 Hyundai Sonata. Everytime I feel up on gas, my car won't start. In order to start my car, I have to rev my engine, and put my other foot on the brake to shift into gear. For a few minutes afterward, my car acts like its trying to stall out.
Anyone have any ideas as to what could be causing this?

H{ello and welcome

It sounds to me like either your canister purge valve is sticking open or the fuel cut valve ist stuck open

either case i would get a pro to check it out
9 times out of 10 its the purge valve
