Ignition Coil Replacement in Orlando — Fix Misfires, Rough Running & Hard Starts
Your ignition coils create the high-voltage spark that lights the air/fuel mixture inside each cylinder. When one or more coils start to fail, you can get misfires, rough idle, lack of power and an annoying check engine light. At Top Notch Mobile Repair LLC, we provide mobile ignition coil replacement in Orlando, diagnosing the problem and installing new coils right at your home or office.
What Our Ignition Coil Replacement Service Includes
- Scanning the engine computer for:
- Misfire codes (P0300–P030X)
- Ignition and coil-specific trouble codes
- Checking live data to see:
- Which cylinders are misfiring or underperforming
- Short- and long-term fuel trims affected by misfires
- Inspecting:
- Ignition coils for cracks, carbon tracking or burn marks
- Spark plugs for wear, fouling or improper gaps
- Coil connectors and wiring for damage or corrosion
- Performing cylinder balance and swap tests (where appropriate) to confirm a bad coil
- Removing the faulty ignition coil(s) and installing quality, vehicle-specific replacements
- Recommending spark plug replacement if mileage or condition suggests it
- Clearing codes and road-testing to verify smooth power, stable idle and no new misfire counters

Affordable Ignition Coil Replacement Cost
Ignition coil replacement cost depends on:
- Your vehicle’s make, model and engine design
- How many coils are failing and whether a full set is recommended
- Condition of related components (spark plugs, plug boots, valve cover seals)
Before replacing anything, we will:
- Explain which cylinders are misfiring and why
- Show you any visible damage on coils or plugs
- Provide a straightforward estimate for parts and labor
No surprises — just clear information and a targeted repair plan.
Common Signs You Need Ignition Coil Replacement
- Check engine light on with misfire codes (especially on specific cylinders)
- Rough idle, shaking or engine “missing” at stoplights
- Hesitation, stumbling or lack of power under acceleration
- Poor fuel economy and strong fuel smell from exhaust
- Engine feels smooth at lower RPM but breaks up at higher load/speed
- In severe cases, flashing check engine light while driving (active misfire)
Driving for long with severe misfires can overheat and damage the catalytic converter, turning a simple coil repair into a much more expensive job.
💡 Pro Tip
If your vehicle has high mileage and multiple original coils, it’s often smart to replace coils and spark plugs together. Fresh coils on worn plugs — or new plugs with weak old coils — can lead to repeat misfires. Doing them as a set can save time, labor and future headaches.
