What is the idle manifold pressure on a 1996 ford mustang gt?

I need to know what the idle manifold pressure is on a stock 1996 ford mustang with the 4.6L V8 2valve. Non PI intake. Also what is the manifold pressure at full-throttle?|||16-18" Hg at idle - at full throttle, it will depend on the engine load and rpm's. Initially, it's close to zero.
