Meltedpanda, Sorry, but I have not done much of anything yet. I don't want to dig too deep until I get the service manual - about a week from now.
From my reading, I see the possibilities as the OVP, the temperature senser, a vacuum leak, or gremlins. I just replaced the battery so I am assuming the previous owner had to jump start the car and warm it up before I got there to look at it, so the OVP is a strong possibility.
