i just found out i have a dead coil pack on my 96 2.2L....I have a lot of spare packs, but i know some are dead aswell and some are good, but i dont want to install one and find out that one too doesnt work, changing those things on 2.2's are a pain. Is there anyway to test them with a volt meter? what setting do i use on the meter and what reading should i be looking for. Thanks in advance
