What are the Symptoms of Bad or Failing Spark Plugs?

The internal combustion engine requires an ignition source to function. Spark plugs provide that ignition sourcing by igniting the air and fuel mix in an engine. This ignition creates an explosion that powers the vehicle and propels it forward. These explosions agitate the pistons that in turn rotate the crankshaft, moving the car forward. Spark plugs create these explosions by creating electrical arcs to uncovered leads, igniting fuel in the engine. Spark plugs are constructed from durable materials like high-nickel alloys and aluminum oxide ceramic. Despite the durability of spark plugs, they do wear down over time. There are extended-life spark plugs that are manufacturer-specific. These spark plugs have life spans up to 100,000 miles. The most common issue of spark plug failure is the widening of the gap between the two leads. This leads to an efficiency reduction and possible misfiring. Spark plugs can also corrode to the point where they do significant damage to the interior of a ... read more
