There are several reasons why spark plug wires may pop off. Here are some of the most common causes:
1. Loose connection: One of the most common reasons for spark plug wires to pop off is a loose connection. When the spark plug wire is not securely attached to the spark plug or the distributor cap, it can easily pop off due to the pressure and vibrations within the engine compartment. This can happen if the wire is not properly seated or if it becomes loose over time.
2. Worn-out or damaged wires: Over time, spark plug wires can wear out or become damaged. This can happen due to heat, exposure to chemicals, oil leaks, or general wear and tear. When the wires are worn or damaged, they may not be able to securely hold onto the spark plugs, causing them to pop off.
