Bp idle rev and stall.

I been working on my car trying to get it back running good to driver everyday. I only waiting for tires to come in. I usually crank it daily to let it warm up and make sure everything is running good. Yesterday it did great. Today I started it let it run for about 5 mins it done great. I decided to rev it a little not much just over 1200 rpms and when I take foot off gas it tries to die. If I hold foot on gas it will smooth out until I remove it again. It will cut off if I let it. I popped the hood and played with air intake hose some and started it back it ran fine until I rev it again any idea what it could be?

Forgot to mention after it does this it hard to get to start back.

I just adjusted the idle up a bit and it did fine again. Seems to be ok. Still seeing of anything I need to check?

Still acting up. Only when you rev it up though. After that it acts like it starving for something.
