I started my CDI up last Sunday night around 2am at Dulles airport in Washington, ambient temp was 17F at the time and the car had been sitting for over a week so it was as cold-soaked as it could be.

In spite of the fact that we almost immediately were at 60MPH on the way home it still took a good 15 miles before it got up to operating temps, its easy for me to believe that at lower speeds it might take quite awhile for it to get up to temp.

What's really strange is that you almost immediately get heat out of the heater? Apparently there must be some sort of resistance or ceramic heater in play?

It's also quite common for the thermostat to fail in these cars, when I got mine it wouldn't get over about 50-60C unless it was over 60F ambient.
