Why Are Spark Plugs Vital for the Performance of a 2006 Toyota RAV4 Sport?
The underlying mechanism involves the creation of a spark that ignites the air-fuel mixture when the engine is running. If the spark plugs are worn or defective, they may produce a weak spark or fail to spark altogether, leading to incomplete combustion. This not only decreases the engine’s power output but can also cause the vehicle to run rough or stall. In addition, improper combustion increases the buildup of unburned fuel, which can lead to higher emissions and may damage the catalytic converter over time, further impacting the vehicle’s performance and longevity.
