Paul et al:

Thanks for all of the advice. I'm going to need to study this for a while to get my arms around it. I think I need to buy the Bentley SC manual as well.

Here are the symptoms - but I've only had the car 2 weeks so they could still be an anomoly.

When it is below freezing outside, the car starts immediately, with a belch of blue smoke if it has been sitting for more than a day. It idles for a less than 10 seconds at 900-1000 rpm, the the idle increases to approx. 2100 rpm. It will remain at this idle for as 20+ minutes, and may never idle back down to 900.

Twice it has died when being driven without an extensive warmup. Both times it was difficult to start afterward.

Based on the input I'm receiving, I am thinking it is a sticking valve in the AAR, but that is just a guess based on the education I'm receiving from this forum.
