idle drop then unknown noise by injectors

[janks85]

Hey guys, basically what the title says.. my car will start up and either just randomly or when i rev high the idle will drop low, vaccum will drop to about -10 or lower and i hear a tick/hissing near the injectors. Their is no smell of gas and does not seem to have air blowing from any of the injector o-rings. Then all of the sudden the idle will even out and vaccum will goto about -15/-16 and idle fine for a bit then during a rev or randomly again it will happen, has anyone had a problem occur like this..any help it greatly appriciated
