99' S50 PO410 code
 

I continue to have this code though I have now done a complete tune up. Once I have reset my check engine light it reappears after setting at a light and auto starts to suddenly miss for a few seconds. This is mostly noticable while setting still but you can also tell it slightly when picking up speed. Some one suggested that it could be a vacuum leak. Another says maybe a partially stopped up fuel injector. Does anyone have a clue?

Thanks, MBD

I have the codes but do not know what would cause this problem. Has anyone else found out what their problem was? I have researched the board and read over others who have had similar problems but have not found anyone who has repaired the problem. MB wants $95 to tell me the same code I already know about.
