Your vehicle’s spark plugs may be small, but their role is critical to how your engine runs. When spark plugs start to fail, they can cause a host of issues—from rough starts to poor fuel economy and even serious engine damage.
At Urban Lube Calgary, we specialize in diagnosing and replacing faulty spark plugs as part of our expert automotive repair services in Calgary. In this blog, our technicians walk you through the key signs of spark plug trouble and when to take action.
What Do Spark Plugs Actually Do?
Spark plugs ignite the air-fuel mixture in your engine’s combustion chamber, making it possible for your engine to run. Over time, they can wear out due to heat, carbon buildup, and age—leading to misfires and reduced performance.
Top Warning Signs Your Spark Plugs Are Failing
1. Trouble Starting the Engine
If your engine takes longer to start or cranks unevenly, your spark plugs may not be firing properly. This is especially common during Calgary’s cold winters when engine components are under stress.
2. Increased Fuel Consumption
Worn spark plugs can’t burn fuel efficiently, causing your engine to compensate by using more gas. If you’ve noticed you’re at the pump more often, it may be time for a spark plug inspection.
3. Rough Idling or Engine Misfires
Vibrations while idling or misfiring sounds when accelerating are common symptoms of bad spark plugs. Left unaddressed, this can lead to bigger ignition issues or even damage to the catalytic converter.
4. Lack of Power or Sluggish Acceleration
Your car might feel hesitant or slow to respond when you hit the gas. This can happen when spark plugs aren’t providing consistent ignition power.
5. Check Engine Light Is On
A faulty spark plug can trigger your check engine light—especially if it causes engine misfires or emissions problems. A diagnostic check is the best next step.
When Should You Replace Your Spark Plugs?
Generally, spark plugs should be replaced every 30,000 to 100,000 kilometers, depending on the type of plugs and driving conditions. In Calgary, frequent cold starts, short trips, and traffic congestion can shorten their lifespan.
At Urban Lube Calgary, we recommend regular inspections as part of your routine maintenance plan.
