check for vacuum leaks and make sure throtlebody plate is clean, use throtlebody cleaner and an old tooth brush to clean, if problem is still there then replace the valve (idle air control valve ).

1991 f150 idles rough but when u give it gas it gets better

Here are a few things that might help.
1. Check your spark plugs. make sure the gap is right and they are not worn out.
2. Check your distributor cap and rotor for build up on the contacts.
3. Check your spark plug wires, make sure they are on the distributor and spark plug tightly. also check them for damage ie. heat, knicks, scrapes, etc.
4. intake idle control valve. these do cause your symptoms and are easy to replace.

hope this helps ~ Zach
