- 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 2013 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:
- 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.
- 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.
- 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.
- Brake pads look thin: You may be able to visually check your brake pad thickness to determine if they need replacement.
What are the initial diagnostic steps to take for a rough idle in a 2013 Dodge Journey?
When faced with a rough idle in your 2013 Dodge Journey, it's essential to adopt a systematic diagnostic approach that begins with the basics. Start by ensuring that your battery and alternator are in good working condition, as electrical issues can significantly impact engine performance. Next, utilize a diagnostic scan tool to check for any trouble codes, which can provide valuable insights into potential problems such as issues with the mass airflow sensor or throttle position sensor. Following this, inspect the air intake system for vacuum leaks, as even minor cracks in hoses can lead to significant idling issues. Cleaning the throttle body is another critical step, as a buildup of dirt can disrupt airflow and affect engine performance. Additionally, evaluate the fuel system for blockages and consider using a fuel system cleaner to maintain optimal function. Don’t overlook the condition of your spark plugs and ignition coils, as worn components can lead to misfires and rough idling. Lastly, check the crankshaft position sensor and other related sensors for any signs of damage or poor connections. By methodically working through these steps, you can effectively identify and address the root cause of the rough idle, ensuring your Dodge Journey runs smoothly. If the issue persists after these checks, seeking professional assistance may be necessary for a more in-depth diagnosis.
What are the common causes of a rough idle in a 2013 Dodge Journey?
When dealing with a rough idle in a 2013 Dodge Journey, it's essential to consider several common problems that may be affecting the vehicle's performance. Fuel system issues, such as a failing fuel pump, clogged fuel filter, or dirty fuel injectors, can disrupt the proper fuel-air mixture, leading to an unstable idle. Additionally, low fuel pressure can exacerbate these symptoms, making it crucial to check the fuel system components. The air intake system also plays a significant role; vacuum leaks can disturb the air-fuel mixture, while a dirty or malfunctioning throttle body can restrict airflow, both contributing to a rough idle. Ignition system components, including spark plugs, ignition coils, and spark plug wires, should not be overlooked, as their wear can lead to misfires. Furthermore, sensor and electrical issues, particularly with oxygen and MAP sensors, can provide incorrect data to the engine computer, further complicating the idle problem. Mechanical issues, such as worn motor mounts or problems with timing belts, can also manifest as vibrations felt during idle. Lastly, using contaminated fuel or issues with the ignition switch can lead to intermittent rough idling. To effectively diagnose the problem, utilizing an OBDII scan tool to check for error codes, inspecting vacuum hoses, and assessing fuel pressure are recommended steps that can help pinpoint the underlying cause.
