Your ignition coil is a small engine component that has lots of responsibility. By transferring power from your battery to the spark plugs, an ignition coil lights a vehicle’s fuel and allows it to run.

If your ignition coil fails, your engine can’t do its job. Faulty ignition coils can be a major safety hazard if not taken care of and eventually lead to expensive repairs

Drivers near Mission Viejo, Rancho Santa Margarita, and Newport Beach may experience the following five symptoms if their ignition coils need replacing.

Your Vehicle Backfires

Ignition CoilDoes your car exhaust smell like gasoline or release black smoke? If so, your vehicle is backfiring, or releasing unused fuel through your exhaust system.

Vehicles backfire for a number of reasons, including faulty or worn ignition coils. Backfiring can be a danger to your safety, so have a body shop inspect your engine to determine whether your ignition coil needs to be replaced.

Fuel Economy Decreases

A failed ignition coil could be eating away at your gas mileage. When this occurs, your vehicle is using more fuel to make up for the inadequate transfer of power between your battery and spark plugs.

If you’re making more trips to the gas pump but haven’t changed your driving routine, have a mechanic inspect your engine for damage to your ignition coil.

Engine Misfiring

When your engine misfires, you could experience vibrating, a loss of power, decreased fuel economy, or a rougher ride while driving. Other times, it may feel like your vehicle is stalling or about to break down.

An engine could misfire for several reasons. Your ignition coil might be the culprit, but it’s important that you check with your mechanic to diagnose the problem and get it repaired.

Vehicle Stalls or Doesn’t Start

If a car doesn’t start due to a failed ignition coil, your engine’s spark plugs aren’t receiving enough charge from the battery. A mechanic can figure out why your vehicle isn’t starting, but we have a suspicion that your ignition coil needs to be replaced.

A Check Engine Dashboard Light Appears

It’s never fun when your check engine light appears. But when it does, there’s a good chance that your engine’s ignition coil isn’t performing correctly.

Anytime you notice your check engine light, schedule a maintenance appointment immediately. There could be several mechanical problems with your engine and only an experienced professional can diagnose the exact cause.
