What the heck does this code mean?

So anyway, I bought this really nifty little OBD 2 reader and plugged it up to my car the other day. After all, I've been plagued with the check engine light for two years and since I live in Spain, I couldn't exactly run the old Monte down to the Chevy dealership. So, my reader throws four codes, three of which were related to when my battery was discon-nected. My reader cleared all the codes and for 2 whole days I was blissfully "engine light" free. Then, it came back on. So, I hooked up the reader again and I got that mysterious 4th code again. Now, my main problem here is that the code, 2655, doesn't appear in my little code book and I can't seem to locate it online. If anyone knows where I can find code listings and their remedies, it would be very, very helpful. By the way, the car is a '96 Monte LS. Thanks for listening to my boring little narrative and thanks in advance for your help. Dave Shamburger
