Check Engine Light
No one likes to see their car's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. At BJ's Automotive, we can pull the code and diagnose the problem for you. Give us a call at 805-527-7741 or stop by the shop for our expert assistance.
Fuel Injection
Fuel injection is a system for admitting fuel into an engine. Since 1990, fuel injectors have completely replaced carburetors as the primary means of getting gasoline into the engine. A fuel injector atomizes the fuel by forcibly pumping it through a small nozzle (under high pressure). Failure of the fuel injection system means poor performance and ultimately destroys the engine.
Ignition
Your vehicle's ignition system is responsible for starting the engine by delivering an electrical spark that ignites the air-fuel mixture in the combustion chamber. Issues can involve a worn ignition switch, a faulty ignition coil or broken or corroded wiring. These problems can lead to symptoms like the engine failing to start, intermittent stalling, dashboard warning lights, or even complete power loss while driving.
Ignition Wires & Cables
These vital parts transfer the spark from the ignition coil to spark plugs that ignite the mixture of fuel and air. The mixture starts the engine. Over time, ignition wires and cables get weak and break down. This makes it impossible for the spark to reach the engine cylinders. This results in the engine misfiring. Common symptoms of faulty ignition cables and wires are: poor gas mileage, engine misfires, engine light is on, and engine vibration.
Oil, Lube, and Filter
To keep running smoothly, your car highly relies on oil, lube, and oil filters. Oil helps in lubricating, cooling, and cleaning the internal engine components. With time, motor oil becomes contaminated. Your car needs an oil, lube, and filter change every three months (or 3,000 miles) in order to function optimally.
Spark Plugs
A spark plug delivers electric current to the combustion chamber from the ignition system. Spark plugs that haven't been changed for a long time can cause ignition problems. At BJ's Automotive, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 805-527-7741 or visit BJ's Automotive today.
Spark Plug Related FAQs
How do you know when a spark plug needs to be replaced?
The most common sign that a spark plug needs replacing is an engine that hesitates during acceleration. Other warning signs may include engine misfires during startup, rough idling, sluggish acceleration, declining fuel economy, and engine knocking.
What else should I replace when replacing spark plugs?
If you're considering having your vehicle's spark plugs replaced, there's a good chance the spark plug wires should be replaced as well. Ignition wires become brittle over time, and worn wires can lead to engine misfires, poor performance, and reduced fuel economy.
Check Engine Light FAQs
What could cause a check engine light to come on?
Come by BJ's Automotive and we can diagnose the reasons for a check engine light turning on. It can range from something serious like a faulty catalytic converter or potential engine failure to something simple like a loose gas cap or the need for a routine 50,000- or 100,000-mile manufacturer maintenance service.
Is it okay to drive with the engine light on?
The short answer is no. The longer explanation is that the light may indicate a serious engine problem, and continuing to drive as if nothing is wrong could result in much more expensive repairs. A check engine light means you should have your vehicle inspected as soon as possible by a professional at BJ's Automotive in Simi Valley.
What is the most common problem with my check engine light?
A loose gas cap is one of the most common reasons a check engine light comes on. However, the best way to determine the exact cause is to have a technician at BJ's Automotive read the diagnostic code stored in your vehicle's onboard OBD computer.
What does a solid check engine light mean?
A steady check engine light generally indicates a non-emergency issue that still needs attention. Come by BJ's Automotive and we'll help diagnose and resolve the problem before it becomes more serious.
What does an intermittent flashing check engine light mean?
A flashing check engine light is a warning of a potentially severe problem that requires immediate attention. Get your vehicle to an auto repair shop as quickly as possible, or safely park it and arrange for a tow to your preferred repair facility to avoid further engine damage.
