3.4l 1996 vacuum testing

[Zebe9]

hi guys
i 've just replaced LIM and the upper rest, still however got intermittent P0304 misfire. New spark plugs, wires, vacuum lines chcecked-OK, vacuum modulator-new etc. Everything-I suppose-has been checked.
Only things I suspect now are: i.coil (but why?-only one cylinder misfire)
or camshaft position sensor. Nothing more comes to my mind...
This car flushes my wallet and makes me sick....

Please help-anyone experienced such helpless problem ?

Anybody knows correct vacuum figures for this engine?
