Bouncing Revs at start up
Today I drove the 928 about 250 miles (mostly highway, mountains) in 100 degree heat, When I returned into town I stopped for 10 mins.
When I started the car the revs "bounced" from 300-800 and the !warning! light was flashing. I was going to shut it off but then everything was ok. The temp was at the halfway mark.
The car ran fine back home so I turned off the car waiting about 5 minutes and tried to start it again. The car started for a second and stalled, I tried again and it did the same thing as the first time with bouncing revs. I shut it down and decided to post.
Any thoughts?

Hot start and idle after hot start problems can be caused by a MAS on the way out.
Let it cool with the hood open for 20 minutes or so. I'll bet it will start.
