Engine Light Comes on on 1996 Lincoln Town Car

Engine light comes on and book says it may be gas cap, so we take it off and re-install it and in about 3 to 4 days light goes off. Should we replace the gas cap? it has happened twice.

How often does the light come on? Are you finding the gas cap loose or not installed correctly when the light is on?
