2014 Kia Soul 1.6L Base Spark Plug Replacement in Murfreesboro, TN – Real Mobile Mechanic Experience

Recently, I completed an on-site spark plug replacement on a 2014 Kia Soul 1.6L Base in Murfreesboro, Tennessee. The customer contacted Mobile Mechanic Co after the vehicle developed a check engine light and began running rough due to an engine misfire.

One of the most important parts of any repair is performing an accurate diagnosis before replacing parts. In this case, the diagnostic process revealed multiple trouble codes, allowing the customer to make an informed decision about which repairs they wanted to complete.

Customer's Concern

The customer noticed the vehicle was experiencing:

• Check engine light illuminated

• Rough engine idle

• Engine misfire

• Reduced engine performance

They wanted to determine the cause of the problem and have the vehicle inspected at their location.

On-Site Diagnosis in Murfreesboro, TN

After arriving, I connected my professional scan tool and performed a complete diagnostic inspection.

The vehicle had the following diagnostic trouble codes:

• P0302 – Cylinder 2 Misfire Detected

• P0420 – Catalyst System Efficiency Below Threshold (Bank 1)

• P0441 – Evaporative Emission (EVAP) System Incorrect Purge Flow

Based on the inspection and the condition of the ignition components, I recommended replacing the spark plugs as part of the repair for the cylinder 2 misfire.

I also discussed the additional diagnostic findings with the customer. The P0420 code indicated that the catalytic converter system was not operating within its expected efficiency, while the P0441 code pointed to an issue within the EVAP system that would require further diagnosis and repair.

After reviewing the recommendations, the customer chose to proceed with the spark plug replacement only and declined repairs related to the catalytic converter and EVAP system at that time.

The Repair

For this service, I completed:

• Removed the worn spark plugs

• Installed new spark plugs

• Inspected the ignition system

• Cleared diagnostic trouble codes

• Verified engine operation after the repair

After completing the service:

✅ New spark plugs installed

✅ Engine performance improved

✅ Misfire concern addressed based on the requested repair

The customer was informed that additional repairs may still be needed to address the remaining diagnostic trouble codes if the warning light returns or other symptoms continue.

Understanding the Diagnostic Trouble Codes

P0302 – Cylinder 2 Misfire

A cylinder misfire occurs when one cylinder does not burn the air-fuel mixture correctly. Common causes include:

• Worn spark plugs

• Faulty ignition coil

• Fuel injector issues

• Compression problems

• Vacuum leaks

Early diagnosis helps prevent prolonged misfires, which can contribute to catalytic converter damage.

P0420 – Catalyst System Efficiency Below Threshold

This code indicates that the catalytic converter is not performing as efficiently as expected. Possible causes include:

• A worn catalytic converter

• Damage caused by prolonged engine misfires

• Exhaust leaks (depending on the situation)

• Other engine performance issues affecting emissions

Proper diagnosis is important before replacing the catalytic converter, since other engine problems can contribute to this code.

P0441 – EVAP System Incorrect Purge Flow

This code points to an issue within the evaporative emissions system. Potential causes include:

• Faulty purge valve

• Damaged EVAP hoses

• Loose or damaged connections

• Other EVAP system component failures

Additional testing is often required to identify the exact cause.
