Customer Complaint
I received a call from a customer in Nashville about their Dodge Journey running rough and not accelerating like it used to. They mentioned the issue had gradually gotten worse over time.
They also noticed:
Rough idle when stopped
Hesitation during acceleration
Decreased fuel efficiency
Occasional engine shaking
These are common symptoms I see when spark plugs are worn out.
Diagnosis Process
When I arrived, I performed a scan and basic inspection.
Findings:
Misfire-related symptoms consistent with worn spark plugs
No major ignition coil failure at the time
Spark plugs showed visible wear and carbon buildup
On Dodge Journey models, spark plugs are a routine maintenance item, but if they’re overdue, performance can drop noticeably.
The Repair
Spark plug replacement can vary slightly depending on engine type, but proper installation is key to performance.
Steps performed:
Accessed ignition coils and removed them carefully
Removed old spark plugs
Installed new, properly gapped spark plugs
Reinstalled ignition components
Cleared any stored codes and tested performance
Total time on-site was about 1–1.5 hours.
Result
After the replacement:
Engine idle became smooth
Acceleration improved
No more hesitation
Overall performance restored
The customer noticed the improvement right away.
Why Spark Plugs Wear Out
Spark plugs naturally wear over time due to:
Heat and combustion cycles
Carbon buildup
Extended service intervals
If not replaced on time, they can lead to:
Engine misfires
Poor fuel economy
Reduced power
Hard starting
