In order for your Ford vehicle to start, you need ignition. That doesn't happen without the factory spark plugs.
How Spark Plugs Work
When you turn the ignition key or press the "Start" button, an ignition switch activates. That compels the battery, starter motor, starter solenoid, and ignition coil to work together and produce a small electric charge that's captured in the plugs' leads. The leads then shoot an arc of electricity across a gap. That electricity combusts the mixture of oxygen and fuel in your engine, producing the power you need.
How to Spot Spark Plug Issues
Unfortunately, spark plugs may lose effectiveness. Maybe the gap has grown too wide, or they've grown corroded with age. Whatever the reason, they'll need replacing at that point. Signs of trouble include:
- Misfiring engine
- Trouble starting
- Rough engine idle
- The "Check Engine" light comes on
