If these steps don’t solve the problem, you have a bad ignition module that will need to be replaced. Sometimes even new ones are bad.
What happens when the spark plug is too big?
On a COP (Coil on Plug) or coil pack car, the coil has a rated “breakdown voltage.” If the spark plug gap grows too large, then the voltage to fire the plug will exceed the breakdown voltage. When this happens, the voltage will arc inside the coil and eventually destroy it.
What makes a spark plug not fire on a coil pack?
Carbon deposits act like resistors effectively delaying the spark. A plug with worn electrodes would also fire late. But on a coil pack driven car, like the Corolla, firing happens by computer and is completely independent of spark gap distance.
