CCV replacement didn't solve my cold start problem. I still got a flashing SES light after about 10 seconds of idling when cold. Shut it off, restarted and it went away. I guess it got a little better as it actually went away with one restart instead of a restart and holding the RPM's up for 2 minutes.

I'll give the "heat" thing a try to see if that helps.
