Is Your Town Car Running Rough? It Could Be an Ignition Coil
A failing ignition coil is one of the most common issues on the Ford 4.6L V8 engine found in your Town Car. Because each cylinder has its own coil, the failure of just one can cause noticeable problems. The symptoms are often very clear and point directly to the ignition system. If you're experiencing a rough idle, hesitation when you accelerate, or a new and unwelcome vibration, a bad ignition coil is a likely culprit.
Choosing the Right Aftermarket Ignition Coil
When replacing ignition coils, you don't have to buy expensive OEM parts to get your Town Car running smoothly again. High-quality aftermarket brands can provide excellent reliability and performance. However, it's wise to avoid the cheapest, no-name options, as they often have high failure rates. Here’s a breakdown of the brands available:
- OEM-Equivalent (Good Quality): Brands like Denso and Hella are known for making parts that meet or exceed original factory standards. Denso is a well-regarded OEM supplier for many car manufacturers and is often recommended as a reliable alternative to the original Motorcraft part. These are a great choice for a daily-driven vehicle, offering a solid balance of quality and price.
- Performance (Higher Output): Brands such as MSD and Accel market their coils as performance upgrades. MSD, in particular, has a generally good reputation among performance brands for providing a stronger spark, which can lead to a smoother idle and better throttle response. While these benefits are most noticeable on modified engines, they can still be a quality replacement for a stock Town Car.
- Standard Aftermarket (Varies): Some brands fall into a budget-friendly category. While they offer a low initial cost, their long-term durability can be inconsistent compared to OEM-equivalent or performance brands.
Pro Tip: Replace the Spark Plugs at the Same Time
If you're replacing an ignition coil, it's the perfect time to also replace the spark plug in that cylinder. A worn-out spark plug can put extra strain on a new coil, causing it to fail prematurely. If your vehicle has over 100,000 miles and the original coils, it's a good idea to replace all eight coils and plugs at once 🎬 Follow this video to replace all eight coil packs yourself. for preventative maintenance.
Known Issues, Recalls, and Bulletins
The 2006-2011 Lincoln Town Car has no specific recalls or widespread Technical Service Bulletins (TSBs) directly related to ignition coil failure. However, Ford did issue TSB #07212, which discusses the repair procedure for damaged spark plug threads in the cylinder head, noting that this type of repair is not covered under warranty. While not a coil issue itself, it's related to the job of replacing spark plugs, which is often done at the same time as coil replacement.

Frequently Asked Questions (FAQ)
Should I replace all 8 ignition coils at once?
If your Town Car has high mileage (over 100,000 miles) and one original coil fails, the others are likely near the end of their service life. Replacing all eight at once is good preventative maintenance and can save you from future breakdowns. If you're on a budget, you can replace only the failed coil.
How do I know which ignition coil is bad?
If your check engine light is on, a code scanner will point to the specific cylinder with the misfire (e.g., P0304 for cylinder #4). If there's no code, a common diagnostic trick is to swap the suspected bad coil with one from another cylinder. If the misfire moves to the new cylinder, you've confirmed the coil is the problem.
🎬 Watch this guide on diagnosing and replacing a bad coil.Is this a difficult job to do myself?
No, replacing the ignition coils on the 4.6L V8 is a very straightforward and common DIY repair. Each coil is held on by a single 7mm bolt and is easily accessible. The entire job for one coil can be done in under an hour with basic hand tools.
🎬 See how to replace an ignition coil on your Town Car.What does a P030x code mean?
A code like P0301, P0302, etc., is a generic OBD-II code that means "Cylinder X Misfire Detected." The last digit tells you which cylinder is misfiring. For example, P0305 indicates a misfire on cylinder 5. This is the most common code associated with a failing ignition coil.
Is it okay to drive with a bad ignition coil?
You can drive for a short distance, but it's not recommended. A continuous misfire can cause unburnt fuel to enter the exhaust system, which can quickly damage the expensive catalytic converter. If your check engine light is flashing, you should pull over as soon as it is safe to do so.
