I guess we can all rest assured that the ticking noise is "normal" and they all do it, but I'm a little skeptical.
I've owned many FI cars and have never heard that kind of racket from the injectors.

Just to clarify, the noise happens only when cold (like a cold start) and is most noisy when in gear, under load and given a little gas. The colder it is, the noisier it is, am I correct?

I know I'm new here and I'm not trying to be a jerk, but who told you summerwind that is was the injectors? A Toyota technician or dealer?

EDIT:
I just talked to my dealer's service department and I barely got through describing the problem before he said it's valve train noise and is normal and they all do it.
so, FWIW
