In my RX330, I hear a ticking noise from the engine.

When in idle, the engine produces a noticeable (and quick) "tick, tick, tick..." noise...like the clock sound from "60 Minutes". Am I hearing the cylinders, belt, or what?

Clearly I have no automative knowledge so let's clear that up right away.

faint ticking sound is normal noise emitted from healthy fuel injectors doing their job.

louder than a faint ticking... something else..

fuel injector tick should be constant when at idle, not varying in sound, ie: intermitant
