Cold Start RPM Spike?
MY GS350 will initially idle at (about) 1600RPM when I first start it up after having it sit overnight. It'll stay at this RPM for about 5-8 seconds and then suddenly spike to about 1900RPM (these numbers aren't exact as I don't really recall what they are, really) and slowly decline as it warms (if I let is sit there and warm up, which is rare).
My question is, does anyone else's 350 do this?

this is normal for me in the winter*
not sure what temperature will cause this, but usually anything below freezing and the RPMs will spike until the engine temp gets to 40%.
I keep my car in a garage and it still does this, so I can only imagine how bad it may be for people who park outside when it's cold.

It spikes up and down a bit around 1200-1500 for the first couple of minutes, then a few more minutes of driving it stays around 1000, and when fully warmed up settles at around 600.
