Here is a very informative video on how to test an ignition coil module and ignition coil on a 2.2 ecotec. I assure this works for other motors too. It shows you how to do it with a scope, test light, and volt meter. I am going try this tomorrow. Figured it would help other people on here and save some time and money since it is so easy.
