Default Re: Analyzing ignition misfires - a picture shows why the Casper's tester works!

Scott I bought me one of those coil testers from caspers and for some reason it does not work. I called caspers about this and they said something about that it might not work on aftermarket coils. I also noticed that not all of the bolts line up on the coils. I have to hold the tester in place otherwise it will not make contact with all the coils. Have you had this problem and is the factory coil made by AC Delco. Autozone only has a Duralast brand and Oreilly's carries the AC Delco, Master Pro, and BWD brand. Which one would you recommend. Thanks
