Your Honda vehicle needs ignition to start. In order to get that ignition, your factory spark plugs need to work properly. They create that initial flash that kindles the air/fuel mix in an internal combustion engine.
How Spark Plugs Work
Spark plugs generate that flash, or spark, by firing an arc of electricity across a gap between their two leads. If your Honda is an older model that's powered by a diesel engine, though, you don't have spark plugs. Instead, your engine is equipped with glowplugs. These have a heating element in the tip. When it gets hot enough, it ignites the mist of fuel that's sprayed into the cylinder, limiting cranking time.
How to Tell Your Spark Plugs Are Failing
Even the highest-quality spark plugs can eventually go bad, whether due to corrosion or the gaps widening too far to produce an effective spark. Here are some signs to look for:
- Engine misfires
- Unsteady idling
- Worsening fuel economy
- Your "Check Engine" light comes on
It's natural to mistake some of these signs for a failing alternator. Before you make that assumption, though, check your plugs. They're far easier and less expensive to replace. Doing so is simple.
