damn... primary being 1st one correct?

anyone have any ideas on what may have caused it to go out? same exact code is being thrown on my brothers car, which had the headers that i now have, in it.

i feel noobish asking these questions ...

has anyone ever seen a code that does not start with a P?? i recently read the codes on my 1996 civic and one started with c and te other started with k i think.... i'll try to get them again and get the whole code.
