When an ignition coil fails, one cylinder stops firing — and your engine shakes, loses power, triggers a check-engine light, and burns extra fuel. Superior Auto Solutions, LLC uses live scan data and swap-testing to pinpoint the exact failed coil before replacing it. No shotgun parts-cannon approach.
Our Approach
- OBD-II scan to identify specific misfire codes (P0301, P0302, etc.)
- Live misfire-counter review
- Coil swap-test to confirm the failed unit
- OEM or OE-quality coil installation
- Spark-plug inspection (we often recommend doing both together)
- Post-repair road test and recheck
Signs of a Failing Coil
- Rough idle or shaking at a stop
- Hesitation under load, especially under hard acceleration
- Check-engine light flashing (do not drive — this damages the catalytic converter)
- Loss of fuel economy
- Hard starts in cold or wet weather
