Why Choose Us in Old Hickory
Ignition coil failures in Old Hickory often show up as a shaky idle, loss of power under acceleration, or a P0300-series misfire code. We bring a scan tool, test each coil, and swap only the ones that are actually bad. Most vehicles have one coil per cylinder, so we diagnose the specific cylinder before quoting a flat per-job price.
We're a mobile mechanic in Nashville TN serving Old Hickory and the surrounding metro — the van, the tools, and the parts come to your driveway or parking lot, so there's no tow and no waiting room.

Signs You Need Ignition Coil Replacement in Old Hickory
Drivers in Old Hickory usually call us about ignition coil replacement after noticing one of these:
- Hard starting after the vehicle sits
- Engine surging or dipping at a stoplight
- Fuel smell at the exhaust after idling
- Long crank before the engine finally fires
- Misfire, stumble, or shaking at idle
- Check engine light flashing — that means an active misfire dumping fuel into the exhaust
How We Diagnose and Repair It On Site
When we arrive in Old Hickory, here is what actually happens, in order:
- 1Scan for misfire counters per cylinder rather than treating the code generically
- 2Coil and plug inspection on the affected cylinder, including boot condition
- 3Coil swap test between cylinders to see whether the misfire follows the coil
- 4Plug gap, heat range, and electrode wear checked against spec
- 5Fuel-trim and injector review when the misfire doesn't follow the coil
- 6Cleared codes and a road test to confirm the counters stay at zero
How long the job takes
An hour to two hours in most cases. V6 and V8 engines that need the intake removed to reach the rear bank take longer.
Parts and warranty
Manufacturer-specified plug type and gap with quality coils. Wrong-heat-range plugs are a common cause of a misfire returning within a few months.
What you'll pay
Nothing gets replaced before it's confirmed. We test first, show you the reading, then give a flat price for the repair.
Ignition Coil Replacement in Old Hickory — FAQs
Do all the coils need replacing if one failed?
Not necessarily. If the others test fine and are low mileage, replacing the failed one is the correct repair. On a high-mileage engine where one has already gone, replacing the set is often the better value — we'll give you both numbers.
Will a tune-up fix my rough idle?
Sometimes. Rough idle is also caused by vacuum leaks, dirty throttle bodies, and failing sensors, which is why we read misfire data per cylinder before selling a tune-up.
Do I need to bring my car anywhere for ignition work in Old Hickory?
No. This is a mobile service — we drive to your address in Old Hickory with the tools, the tester, and the replacement part. Driveway, apartment lot, office parking, or a roadside shoulder all work as long as the vehicle is on reasonably level ground and we can get a van beside it.
