Will start up and drive but will not stay on unless I keep giving it gas. Maybe a filter issue? I'm not sure.

First eliminate all vacuum or air leaks in the system (very important)

. You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.

How should I go about checking for vacuum and air leaks?

The best way is by using a smoke machine but if you can't d that you can listen for hissing or spray some carb cleaner around while listening for the pitch of the engine to change.
