The most common reasons a 2019 Dodge Journey has rough idle are a vacuum leak, an issue with the spark plugs, or a problem with the ignition coil.
  • Spark Plugs: Worn or fouled spark plugs can lead to misfires, poor fuel economy, and difficulty starting the engine.
  • Ignition Coil: A faulty ignition coil can cause misfires, rough idling, and difficulty starting the engine due to inadequate spark delivery to the spark plugs.

How much does it cost to fix a 2019 Dodge Journey has rough idle?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

Here are a few common symptoms of worn-out brake pads:

  1. Low brake pad warning light is on: Not all vehicles are equipped with this system, but if yours is, this dashboard indicator light will likely be the first signal it’s time to replace your brake pads.
  2. Brakes start to squeal regularly: This is often one of the first signs of worn brake pads and is caused by a metallic piece built into brake pads for this exact purpose. This part contacts the brake rotor to make a squealing or whining noise when the pads are low.
  3. Brakes make loud grinding noise: If not addressed early enough, your brake pads may get so worn that the metal backing plate of the pad grinds against the metal rotor.
  4. Brake pads look thin: You may be able to visually check your brake pad thickness to determine if they need replacement.

Most often, a brake system inspection will just be a routine portion of manufacturer specified maintenance, and will be performed at mileage intervals. In those cases, there will likely be no symptoms. However, when a brake system makes a funny noise, causes vibration, is hard to use, will not slow the vehicle, prevents the vehicle from driving, makes the vehicle pull to one side, or leaks brake fluid, the vehicle will need a visit dedicated to the inspection of the brake system.

What are the steps to diagnose a rough idle in a 2019 Dodge Journey?

To effectively diagnose a rough idle in your 2019 Dodge Journey, start with the simplest solutions before progressing to more intricate checks. Begin by using an OBD-II scanner to check for any error codes, as these can quickly point you to underlying issues. Next, inspect the spark plugs for wear or fouling, as these are critical for proper engine performance. A clean air filter is essential for optimal airflow, so ensure it is not clogged. Additionally, examine the vacuum hoses for any signs of damage or leaks, which can significantly affect idle quality. Cleaning the throttle body is another important step, as carbon buildup can disrupt airflow. Don’t forget to test the mass airflow sensor, as a malfunction here can lead to an improper air-fuel mixture. Finally, inspect the fuel system, including the fuel filter and injectors, to ensure they are functioning correctly. By following this structured approach, you can effectively identify and resolve the issues causing a rough idle, restoring your vehicle's performance.

What are the common problems that could cause a rough idle in a 2019 Dodge Journey?

When diagnosing a rough idle in a 2019 Dodge Journey, it's essential to consider several common problems that could be affecting your vehicle's performance. One of the primary culprits is a dirty or clogged air filter, which can significantly restrict airflow to the engine, leading to an uneven idle. Additionally, faulty spark plugs are notorious for causing misfires; if they are worn out, they can disrupt the combustion process, resulting in a rough idle. Another potential issue is vacuum leaks, which can alter the air-fuel mixture and negatively impact engine performance. Fuel system problems, such as a clogged fuel filter or a malfunctioning fuel pump, can also hinder fuel delivery, contributing to an unstable idle. Furthermore, a malfunctioning mass airflow sensor may provide incorrect readings, affecting the engine's air intake and performance. Lastly, issues with the Exhaust Gas Recirculation (EGR) valve can disrupt the flow of exhaust gases, further complicating the idle situation. By addressing these common problems through regular maintenance and timely repairs, you can effectively resolve the rough idle issue in your Dodge Journey.

How urgent is it to address the rough idle in a 2019 Dodge Journey?

Addressing a rough idle in your 2019 Dodge Journey should be considered a priority, as neglecting this symptom can lead to a cascade of more serious issues. A rough idle often indicates underlying problems with the engine or related components, which can escalate if not addressed promptly. For instance, dirty fuel injectors or a malfunctioning oxygen sensor can not only diminish your vehicle's performance but also decrease fuel efficiency, leading to higher costs at the pump. Moreover, if these issues are left unresolved, they could potentially cause significant damage to the engine, resulting in costly repairs that could have been avoided with timely maintenance. Therefore, it is crucial to diagnose and rectify the cause of a rough idle as soon as possible to ensure the longevity and reliability of your vehicle, ultimately safeguarding your investment and enhancing your driving experience.
