Would help to know what your are trying to permit and see what config you are implementing.
But, if it almost stops traffic, that would mean traffic is passing?
The implicit deny any any is at the end of all ACLs, and when setting up access restrictions you should configure the rules to be as specific as possible.
For more help please provide a more detailed description of what you are trying to do, and seeing the configuration of your ASA would also help.
