This is a hot start problem. Somewhat unusual with the CIS systems, but in this case, you are probably looking at a new enrichment compensator. They are usually about $375. While you're at it, you might as well replace the injectors as well. I think they're about $28/each from MB. Hope this helps. Oh, by the way, make absolutely sure you are running the highest octane fuel available, preferably Shell 93 or Sunoco Ultra 94.
