Let’s face it: cars can be drama queens. One day they’re purring like kittens, the next they’re coughing, sputtering, or guzzling gas like there’s no tomorrow. If your ride’s been acting moody lately, a failing ignition coil might be to blame. These unsung heroes of your engine’s ignition system are easy to overlook—until they start causing chaos. Let’s break down the symptoms of a coil going bad, why they happen, and what you can do about it.

What Does an Ignition Coil Even Do?

Think of your ignition coil as the middleman between your car’s battery and its spark plugs. It transforms the battery’s low voltage (12 volts) into a jolt of up to 45,000 volts to create the spark that ignites the air-fuel mixture in your engine’s cylinders. Without this spark, your car wouldn’t start, period.

Most modern cars use a “coil-on-plug” system (one coil per spark plug), while older models might have a single coil feeding multiple plugs. Either way, a faulty coil can throw your engine’s rhythm out of whack.

Symptoms of a Coil Going Bad: Don’t Ignore These Red Flags

1. Poor Fuel Economy ⛽

Suddenly spending more time at the gas pump? A weak ignition coil can cause incomplete combustion, meaning your engine burns fuel less efficiently. To compensate, it might dump extra fuel into the cylinders, wasting gas and money. According to the Society of Automotive Engineers, misfires from bad coils can reduce fuel efficiency by up to 30%.

What to watch for:

• Your “miles per gallon” drops noticeably.
• You’re filling up more often, even with your usual driving habits.

2. Misfiring Engine 🔥

A misfire feels like your engine is hiccuping—jerking, sputtering, or even stalling at stoplights. This happens when the coil fails to send enough voltage to the spark plug, leaving unburned fuel in the cylinder. Over time, misfires can damage your catalytic converter (a very expensive fix).

Pro tip: Use an OBD2 scanner (like this one from AutoZone) to check for trouble codes like P0300 (random misfire) or P0351 (coil circuit malfunction).

3. Difficulty Starting 🚗💨

Ever been stuck in a parking lot, turning the key repeatedly while your car groans but won’t start? A dying coil might not generate enough spark to ignite the fuel, especially in cold or damp weather. If this happens alongside misfires, the coil is likely the culprit.

Other Sneaky Symptoms You Might Miss

• Check Engine Light 🚨
  Your car’s computer is smarter than you think. It’ll often detect coil issues and trigger the check engine light. Don’t ignore it—90% of the time, this light signals a problem that needs fixing (Cars.com).
• Backfiring or Rough Idling
  Unburned fuel can ignite in the exhaust system, causing loud pops or bangs. You might also feel the steering wheel vibrate at stoplights.
• Gas Smell or Fuel Leaks
  A faulty coil can leave raw fuel in the exhaust, creating a gasoline odor. In rare cases, pressure buildup from misfires might even cause fuel leaks (Firestone Complete Auto Care).
• Sluggish Acceleration
  If your car feels like it’s dragging an anchor, weak sparks could be robbing your engine of power.

Why Do Ignition Coils Fail?

Ignition coils work hard—they handle extreme heat, vibration, and electrical stress. Common causes of failure include:

• Age: Most last 80,000–100,000 miles.
• Moisture: Leaky valve covers or car washes can fry coils.
• Faulty Spark Plugs: Worn plugs force coils to work harder.

How to Diagnose a Bad Coil (Without a Mechanic)

Symptom	Quick Check
Misfires	Swap the suspect coil with another cylinder. If the misfire moves, replace the coil.
No Start	Test for spark using a spark tester (under $20 at AutoZone).
Check Engine Light	Scan for codes like P0351–P0358 (coil-specific faults).

Can You Drive with a Bad Coil?

Short answer: Not for long. Driving with a faulty coil can:

• Damage your catalytic converter ($1,000+ to replace).
• Cause unburned fuel to wash oil off cylinder walls, leading to engine wear.

If you’re stranded, head straight to a mechanic—or use roadside assistance through your insurance.

Fixing the Problem: Coil Replacement 101

Replacing an ignition coil is a DIY-friendly job if you’re handy:

1. Locate the coil (usually on top of the engine, attached to spark plugs).
2. Unplug the electrical connector.
3. Remove the mounting bolt, pull out the old coil, and insert the new one.

Costs range from $50–$250 per coil, depending on your car. Brands like Bosch and Delphi offer reliable aftermarket options.

Not a DIYer? Sites like RepairPal can estimate local mechanic costs.

Prevent Future Coil Failures

• Replace spark plugs on schedule (check your owner’s manual).
• Fix oil leaks promptly—oil can degrade coils.
• Avoid cheap, off-brand coils.

The Bottom Line

Ignition coils are small but mighty. Catching issues early saves you from costly repairs and keeps your car running smoothly. If you’re spotting symptoms of a coil going bad—like misfires, poor gas mileage, or that dreaded check engine light—don’t wait. Test it, replace it, and get back to stress-free drives.

A recent social media clash between Elon Musk and former Republican congresswoman Liz Cheney has reignited questions about the billionaire’s citizenship and eligibility for political office. Here’s what you need to know about the drama and Musk’s background.

The Cheney-Musk Feud

 

The spat began when Musk criticized Liz Cheney’s early career ties to the U.S. Agency for International Development (USAID), calling it a “criminal organization” and advocating for its abolition. Cheney, a vocal critic of Donald Trump and the MAGA movement, fired back by highlighting Musk’s immigrant background:
“You may be unfamiliar with [America’s history of defending freedom] since you weren’t yet an American citizen.”

Cheney’s jab refers to Musk’s path to U.S. citizenship—a detail that’s now under fresh scrutiny.

---

Is Elon Musk a U.S. Citizen?

 

Yes. Musk was born in Pretoria, South Africa, but moved to the U.S. in 1992 at age 21 to study at the University of Pennsylvania. According to his biography by Walter Isaacson, he became a naturalized American citizen in 2002.

 

• Visa Journey: Musk arrived on a J-1 student visa, later switching to an H-1B work visa (commonly used for skilled foreign workers).

• Political Eligibility: While Musk can’t run for president (the Constitution requires candidates to be natural-born citizens), he could hold other federal roles, such as a cabinet position.

Musk’s Other Citizenships

Musk holds dual citizenship with South Africa and Canada:

• South Africa: His birth country.

• Canada: Through his mother, Maye Musk, who was born in Canada. He obtained a Canadian passport in 1989 and briefly studied at Queen’s University in Ontario before moving to the U.S.

---

What About His Kids?

 

Musk’s 12 children have ties to multiple nationalities:

• Canadian Citizenship: All his children inherit Canadian citizenship through their mothers (Justine Wilson, Grimes, and Shivon Zilis are all Canadian).

• U.S. Citizenship: Kids born in the U.S. automatically gain American citizenship—though this could change if birthright citizenship laws are revised.

---

Why Does This Matter?

 

The debate over Musk’s citizenship comes amid his growing influence in politics. He’s currently advising the Trump administration on cost-cutting measures for federal agencies, including USAID. Critics argue his immigrant background could complicate his role in shaping U.S. policy, while supporters see it as proof of the “American dream.”

Cheney’s comments reflect broader tensions over national identity and political power. For now, Musk remains a U.S. citizen—but the conversation raises questions about how citizenship shapes public perception and political ambition.

Final Takeaway:

While Musk can’t aim for the White House, his global background and citizenship status keep him at the center of political and cultural debates. Whether this fuels his influence or limits it remains to be seen. What’s your take? Let us know in the comments!
