I don't have any issues with the rpms when the car is idling at a stop, but here is what I have noticed:
when I let my foot off the gas, put in neutral and coast, the rpms drop just below 500 and jump back up as the car is slowing down, and as I apply the brakes to completely stop, the car sounds like it is going to stall out.
But when I coast while in gear, and apply brakes at the end, put the clutch in just before coming to a complete stop, rpms are completely normal, no jumping and no stalling sound at all.
Not sure if this is normal for this car, but all the cars I've had have never done this (I have only owned manuals). Thoughts?

My car does exactly this. Two ways I can make the rough idle noise produce
1) >40mph in 5th or 6th. Put it in neutral and let it coast; no gas pedal. Car slows down on its own. Once the car slows past 36-38mph the noise happens. Every single time.
2). >50mph in 5th or 6th. Put it in neutral and apply brake to stop. Once the car slows past 20ish mph the noise happens. Every single time.
Dealer documented it, and I got Scion NA involved. Dealer thinks something is up in the transmission. The last update I got from Scion NA is "no update. Still researching. Will call you back in a week"
My take is that if the car idles long enough it will make the noise (DI/PI switch?) or the transmission does not fully disengage when in neutral causing the lugging (holy shit, but not likely)
