This was the first morning that was really cold and I didn't use the remote start to warm it up.
Pulled out of the drive way, come to a stop with cars in front of me and out of the blue the idle
goes from 700 rpm to about 1200 rpm, I almost hit the car in front of me.
The idle was jumping between 700 and about 1200 rpms every couple of seconds. This lasted
for the next couple of stops and than went away. Only have 1k miles on it.
Is this a known problem, anyone else experience this. I know if I bring it in for service it will be fine.
I'll try an repeat the senario tomowwow. Any thoughts.

Just monitor it and see if it happens again.

This happened to my wifes IS 250. They did a recall for it but it still does it from time to time especially during cold weather.
