351 bogging out when just tapping throttle
 

When im driving while just hitting the gas and not reving it high it wants to stall, but when i hit the throttle hard it revs right back up and is fine until i am just driving normal again. Its hard to explain but it feels like theres no throttle and then all of a sudden boom im spinning my tires

Possible vacuum leak.

I noticed that it only does it when it rains or snows. I have a coolant leak around the intake somewhere so maybe its suckin water
