7 Signs of a Faulty Ignition Coil

Have your car's engine started to lose its energy? Is it coughing and muttering all of a sudden, and slouching along like a sickly invalid? If it is, you may have a faulty ignition coil. The following seven symptoms should prompt you to visit your nearest Chevy dealer at once to have your bad coil repaired or replaced. 

Check Engine Dashboard Light

Modern Chevrolet vehicles have over a hundred sensor modules designed to pick up any kind of trouble, so the first thing you'll notice when an ignition coil falters will often be the check engine light springing to life on your dashboard. This light might point to a variety of possible problems. You'll probably need a technician to determine if an ignition coil or something else is malfunctioning. 

Coughing, Sputtering Sounds

When ignition coils fail to send sufficient electricity to the spark plugs, those spark plugs start misfiring. That means the cylinder won't be burning fuel properly. Instead of a smooth and steady engine rumble, you'll hear it coughing and sputtering as if it's struggling to stay alive. 

Shaking and Juddering

With a bad coil, your misfiring engine will also shake and vibrate strangely. These symptoms will often be worse first thing in the morning and whenever you drive slowly or pause in idle. 

Sudden Stalling 

If an ignition coil has given up the ghost entirely, you may find yourself suddenly stalling while pausing at traffic lights. Needless to say, this can be very inconvenient, especially if your engine struggles to start up again. 

Struggling to Start

Without fully functioning ignition coils, an engine may struggle to start, especially first thing in the morning when a strong surge of electrical voltage is required. Because of this, if it's taking you several tries to get your engine going, consider having your ignition coils checked. 

Reduced Accelerative Power

An engine with one failing cylinder also has lessened power. This will be most obvious when you're trying to gain a quick burst of speed and your car fails to accelerate as it should. 

Poor Gas Mileage

Even though a bad ignition coil can't deliver the ignition sparks as rapidly as it should, the cylinder's fuel injector will keep injecting the same amount of fuel. This results in plummeting fuel efficiency. 

How Frequently To Replace Coils at Your Chevy Dealer

Ignition coils tend to last around 100,000 miles of driving, although this distance can vary depending on coil quality and driving conditions. Anything that puts the engine under more strain may cause your coils to wear out sooner. 

Visit Bacon Chevrolet today to have your car's ignition coils inspected and repaired or replaced. For over 50 years, the Billy Bacon family has been looking after the drivers of East Texas with great vehicles and great customer service.

6 Essential Services Offered by Your Chevy Dealer

Every Chevy owner knows that the secret to longevity is regular maintenance. When a trusted technician carries out routine oil changes, tire rotations, brake repairs, fluid flushes, and all the other vital Chevy services, many of which are outlined below, your car will perform optimally for the entirety of its lifespan. Head to your local Chevy dealer today to have your car cared for by the pros. 6 Essential Services Offered by Your Chevy Dealer Oil and Fluid Flushes The motor oil, coolant, brake fluid, transmission fluid, and other fluids in your car keep its many complex parts working well. Neglecting to change your oil on time could result in serious engine trouble. Likewise, coolant must never be allowed to diminish; the same goes for each other fluid. Your owner's manual can provide a suitable schedule for checking, topping up, and flushing each one. Air Filter Replacements Fresh air is required for the combustion process, which uses an exact mix of oxygen and fuel inside the cylinders. If your engine air filter becomes clogged up with dust, dirt, insects, and other airborne contaminants, the inflow of air will become restricted, harming your engine. The cabin air filter can also become blocked over time. Our technicians can quickly replace both filters for you. Tire Checks and Rotations Your tires should be examined once a month or more to ensure the air pressure remains at the correct PSI. Tires also need to be rotated twice a year at your local dealership to prevent uneven wear; you might coincide this with your oil changes. External Light Inspections Your car's headlights, brake lights, turn signals, and parking lights are vital for safe driving both day and night. A technician should periodically check to ensure that each bulb is shining at maximum brightness. Brake Servicing and Repair As you drive, your brakes will steadily wear down from continual pressure. Brakes should be properly inspected twice a year, and each brake pad and rotor replaced as it nears the end of its useful lifespan. Suspension Tune-Ups The suspension of any car will gradually become knocked slightly out of shape by potholes, curbs, and ordinary wear and tear. This can misalign the wheels and cause other handling issues. Have your shocks and struts inspected twice a year and replaced or realigned as required. Arrange Routine Chevy Services To Fit Your Busy Schedule Keeping track of all the required services can be tricky for any busy vehicle owner. Allow us to help you with that. By scheduling all your routine vehicle services with us, you're ensuring you'll never neglect to look after your engine, brakes, tires, suspension, gearbox, or lights. Your Chevy deserves the best, and that starts with comprehensive maintenance services from a trusted source. Visit Bacon Chevrolet in Frankston, TX, today to have your car serviced by highly qualified professionals.
