Why Choose Us in Franklin

Ignition coil failures in Franklin 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 Franklin 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 Franklin

If you're in Franklin and any of the following sounds familiar, this is the right service:

  • 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
  • Hesitation or a flat spot under acceleration
  • Rough cold start that smooths out once warm
  • Noticeable drop in fuel economy

How We Diagnose and Repair It On Site

When we arrive in Franklin, here is what actually happens, in order:

  1. 1Scan for misfire counters per cylinder rather than treating the code generically
  2. 2Coil and plug inspection on the affected cylinder, including boot condition
  3. 3Coil swap test between cylinders to see whether the misfire follows the coil
  4. 4Plug gap, heat range, and electrode wear checked against spec
  5. 5Fuel-trim and injector review when the misfire doesn't follow the coil
  6. 6Cleared codes and a road test to confirm the counters stay at zero

How long the job takes

A plug and coil job is typically 60 to 120 minutes. Engines that require intake removal to reach the rear bank take longer.

Parts and warranty

We install the plug type and gap the manufacturer specifies and quality coils. Generic plugs of the wrong heat range are a common cause of a misfire returning within months.

What you'll pay

You get a firm quote before any tool comes out of the van. If the diagnosis shows the part you suspected isn't the fault, we tell you that instead of selling you the part.

Ignition Coil Replacement in Franklin — FAQs

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 Franklin?

No. This is a mobile service — we drive to your address in Franklin 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.

How soon can you get to Franklin?

Most Franklin jobs are booked same day or next morning, Monday through Saturday. Text a short description of what the vehicle is doing and we'll come back with an arrival window and a price range before we head out.

Should I keep driving with a flashing check engine light?

No. A flashing light means raw fuel is reaching the catalytic converter, and converters are far more expensive than plugs and coils. Pull over and have the vehicle looked at where it sits.
