Testing the spark plug in action with coil pack removed test
Anyone have any advice on how to proceed with a commercial or homemade test of the spark plugs firing with the coil pack removed? Water is getting into my plug well on #2 cylinder, causing it to arch and thusly miss. I need to see it in action. I know I will need a plug wire that runs from the plug to the coil pack which should also be highly insulated for safety. I just could use some advice on the process. We want to see where exactly the water is coming from. We are not convinced that is is a deep engine problem such as a cracked block or head gasket yet. Surely someone has had this issue.
