OKay SO, My engine blew on my 97 2.o motor about a month ago and I finally picked one up from the junkyard with about 78k on it. I know its a 2.0 aba but it seems minutely different, and I think it has the secondary air pump which mine didnt... im starting to worry that this may be an OBDI engine and not an OBDII. How can i tell which it is?? and would an OBDI engine work with my OBDII setup? Thanks for any help you guys can get me, cuz i dont want to start workin on this new engine and It not bolt up after im done.
