Have you first removed the aeriator to see if it's plugged up?
Disconnected the lines under the fauce and ran some water into a bucket.
I've never once seen water line need to be blown out with air unless it was to winterize them.

One kink in a supply line can cause this.
Old steel pipes for sure can cause it. They rust up from the inside out.
