Clicking from TB

I hear a clicking from the TB when my car idles, i think its frequency increases as RPM does, but Can't hear it over the engine at high rpm's. Is this normal? It runs fine.
Also, how exactly is the injector spray pattern supposed to look?

that is the injectors opening and closing, if its a slight ticking.

spray cone should look like a nice shaken can of spray paint, only clear. smooth and consistant, hitting right above the butterflies on the bore wall.
