On 2003's there is a TSB out. If you call Ford they will send you the gasket kit and pinch bolts needed for this.
No it is not a big job, I believe it takes only 2 hrs but can be done in a very short time. You must remove the intake plenum and replace that gasket, as well as replacing the fasteners that secure it to the upper intake manifold. Torque them to spec.
You may also need to replace your valve cover(s) as part as the TSB, but I believe that by 2003 they had this problem solved. Also, check your fuel pressure regulator vacuum hose for any cracks or leaks.
