There are a number of on-the-car, shadetree tests for your ignition coil, but to definitively determine whether your coil is on the way out, the only proper coil test is with a multimeter. Why? Here's the rundown:
Inside an ignition coil are two coils of wire on top of each other. These coils are called windings. One winding is called the primary winding, the other is the secondary. The primary winding gets the juice together to make a spark and the secondary sends it out the door to the distributor. Either one of these windings can go bad and cause your ignition coil to fail.
