Need Code List, C/E Light, '91 300SE
 

I have a '91 300SE and about 4 years ago, right after I bought it, the check engine light came on. Through this group here I was able to take care of the problem then, an EGR problem (16 flashes, if I remember correctly). Fast forward 4 years, the engine light has come on 2 times (11 flashes), which I am able to reset from the box under the hood with the red LED in it. The problem is that though I can count the flashes, I have no idea what the problem might be because I didn't write down the list and after searching here can't find it either. Does anyone have the code list for my car.

Thanks in advance

Thank you Arthur, that is what I needed and then some, there are more codes than I remembered.
