Default Rpm idling question????

Hey guys my gs430 is back to stock now, but recently i notice that when the car is idling the rpm needle is flucuating very lightly to where i can see it. I took it to lexus, and they said everything is normal. I just wanted to see if thats normal with everyones car.

Air temps can cause some minor fluctuations in the RPM...nothing to worry about. I would probably be a little more worried about it if it were consistently higher or lower rather than fluctuations.

Sounds like a dirty TB. If you had Exhaust/intake before, you prob. coudnt feel difference until now.
