It does store them. The catch is not to shut the engine off, once the light has 
manifested itself. Keep the engine running, open the hood, locate the fuel pump 
relay (the one with the empty fuse holder on top) and insert a spare fuse for ~ 
5sec. Pull the fuse out and wright down the codes. A start of each sequence would 
be 4444.

I have a gut feeling that you'll get an *intake air temp* code, which often 
directs to a broken wiring @ the IC temp sensor. Pretty typical on a 200 with the 
symptoms, that you've just described.
