1999 Mercedes Benz sl500
Engine missing and Check Engine Light Lit

If my 1999 SL500 has been sitting for a day or so it starts with a terrible miss. It acts like it is running on 4 cylinders and the check engine light comes on.
It clears gradually after shutting down and restarting the engine 2 times or so and driving a few blocks but the check engine light stays on. Usually after driving a few miles and making a few stops and starts of the engine the check engine light goes off.
What can be happening?
Any help would be appreciated.

sorry for the OT joke, but the title of this thread reminds me of the old "Is your refrigerator running?" prank call.

I hope you find your engine. When you do, the check engine light should go out.

consider this a free bump
