Spark Plug Service & Replacement at D.E.L. Motors
Spark plugs are vital components in your engine’s performance. Spark plugs ignite the fuel mixture in the engine at the precise moment allowing for optimal horsepower, fuel efficiency, and low emissions. They can become weak and wear out, which is why it’s important to replace them regularly. You can have your vehicle serviced and spark plugs replaced at D.E.L. Motors.
Spark Plugs Replacement Guidelines
Replacing your spark plugs at regular intervals is important to proper engine function. Plugs are usually replaced at 30k, 60k, and 100k miles. Your owner’s manual will give you a schedule for recommended spark plug replacement. Sometimes plugs can fail earlier than they should, and this may be a sign of internal issues with the engine. Letting our team of service professionals diagnose your vehicle can ensure it is operating at its best.
The warning signs of bad spark plugs:
- Failure to start
- The check engine light is on
- Misfires: frequent misfires may damage the engine
- Loss of power -poor fuel economy
- Vibration and/or Rough idle
Operating a Vehicle with Bad Spark Plugs
Your vehicle may continue to run even if you have bad spark plugs. However, continued operation with bad plugs can cause internal engine damage not to mention the loss of horsepower, poor fuel economy, and overall poor performance. Computer-controlled ignition systems often won’t allow the vehicle to start if it is detecting a misfire. It is advisable to replace all the plugs even if only one has gone bad. Plug replacement guarantees even spark distribution and optimal engine performance.
Vehicles have four, six, or eight spark plugs. The best solution is to replace all the plugs at the same time, even if only one plug has gone bad. Others may be weak, causing an uneven amount of spark.
