hello i just changed my MAF sensor on my 87 2.8 and its still giving me a code 34. i checked for vacuum leaks and i checked the fuse on the passenger side but i don't know where the relay is located for the maf sensor. can anyone give me an idea? is it one of the 3 located on the fire wall by the drivers side? if not what are those relays? i know one is for a/c and cooling fan function..

any help is greatly appreciated
