Why does spark plug wire from cylinder keep popping out upon acceleration?

Here are a few reasons why your spark plug wire might be popping out during acceleration

1. Faulty spark plug gap: Check the gap between the spark plug and the wire; it should match the manufacturer's recommendations. If the gap is too wide, it could cause the wire to pop out.

2. Loose spark plug wire: Ensure the spark plug wire is securely attached to both the spark plug and the distributor. A loose connection can result in the wire detaching during acceleration.

3. Damaged spark plug wire: Check for any signs of wear, cuts or breaks in the spark plug wire that may weaken it and cause it to detach during acceleration. Replace damaged wires immediately.

4. Excessive vibration: If your engine is experiencing excessive vibrations, it can cause the spark plug wire to come loose. Inspect the engine mounts and ensure they are in good condition.

5. Oil or coolant leak: Check for any oil or coolant leaks near the spark plug wires. If there is a leak, the oil or coolant could cause the wire to become brittle and detach during acceleration.

6. Incorrect routing: Make sure the spark plug wires are routed correctly according to the engine's manufacturer specifications. Improper routing can lead to excessive vibration or stretching, causing the wire to pop out.

7. Incorrect wire material: Ensure that the spark plug wires are designed specifically for your engine's ignition system. Some aftermarket wires may not be compatible and can lead to connection issues.

8. Defective spark plug: A worn-out spark plug can cause the spark plug wire to disconnect during acceleration. Check the spark plug condition and replace it if necessary.
