Glow plugs have a significant lifespan. However, they eventually deteriorate because of wear and tear. How do you know that your glow plugs are bad? One way is through routine maintenance at a diesel repair shop. Vehicle maintenance enhances its performance and reliability and increases your safety. Besides that, it's also an opportunity to know which car parts are damaged. Take a look at these other signs that you have bad diesel glow plugs.

1. Difficulty Starting the Vehicle

It's very difficult to start a diesel engine if you have bad glow plugs. That's because they won't generate enough heat for the cylinder and ignite the fuel. You can avoid this problem by taking your car for routine maintenance. The mechanic will detect the issue and inform you of bad glow plugs.

Unfortunately, many people don't take this step. According to Automotive Research, about 7.9% of consumers delay routine vehicle maintenance. Millennials, people who own used cars, and owners of cars more than eight years old are more likely to delay routine maintenance than their counterparts. Make it a habit to take your vehicle for regular maintenance to detect such issues earlier.

2. Engine Misfiring

Diesel engines require the right amount of fuel injected at the correct time, leading to combustion. When you have bad glow plugs, the engines are likely to misfire because there isn't enough heat needed for diesel combustion.

3. Poor Acceleration

You may somehow manage to start a diesel engine even with bad glow plugs, but the car won't perform optimally. You'll notice that your car isn't generating much speed no matter how much you floor the accelerator. Nonetheless, other engine problems can cause poor acceleration as well. Take your car to a diesel repair shop for a professional inspection. The mechanic will determine what the exact problem is.

4. Rough Idling

If one or several glow plugs burn out or are damaged, it will become progressively harder to start the engine, causing your car to idle. The exhaust will produce white smoke for several minutes before the car finally starts.
