ECU is shutting down a cylinder (99s320)
What would cause this? Just trying to have a clue before I take it in....

when missfire is detected [those engines have plug wire issues] the ecu shuts down the offending cylinder injector.

Most likely, it's a bad plug-wire set for that cylinder. As David said, there's problems with the "wires".
Saw this first hand and had a hard time believing what I saw at my tech's shop. The plug wire looked ok but it was open! And they only 8" or so, amazing! |

The problem is the resistor boot under the coils..very common on this last of the Waste Spark ignition DIS systems.
Change all 3 of them. [ one under each coil /DIS system] Leave the plug wires alone until you change these 3 coil connectors. Techs change these automatically when doing plugs change on 104's b/c of their failure rate. http://catalog.worldpac.com/mercedesshop/sophio/quote.jsp?clientid=catalog.mercedesshop&cookieid=2AO123CS42BD0O5777&baseurl=http://catalog.peachparts.com/&partner=mercedesshop&year=1999&product=F1010-84561&application=000357360 http://catalog.worldpac.com/mercedesshop/sophio/image.jsp?title=Spark%20Plug%20Connector&url=http%3A//img.eautopartscatalog.com/live/F101084561BER.JPG I would also change the plugs while I was there b/c these great systems still take the Bosch NON Resistor Super Core plugs and they are dirt cheap..use NO OTHER but F8DC4 in 104 DIS engines..they love this plug http://catalog.worldpac.com/mercedesshop/sophio/wizard.jsp?partner=mercedesshop&clientid=catalog.mercedesshop&baseurl=http://catalog.peachparts.com/&cookieid=2AO123CS42BD0OD395&year=1999&make=MB&model=S-320-001&category=F&part=Spark+Plug
