I am in the process of preparing to do a tune up on my 97 with a 5.4 and will be replacing all 8 ignition coils at one time. I already replaced one and i believe that it is going bad already. This was about a year ago. My question is if i went to the junkyard to get the coils off of a newer model what years interchange? I would obviously try to get one that had lesser miles which in turn would be a newer year expedition. So would a 04-05 etc 5.4 coils work on a 97?
Thanks a lot.
