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.

Diesel
Although diesel engines don't require tune-ups and tend to last longer than gasoline engines, they do require regular maintenance. Typical maintenance tasks include:
- Changing the oil & filter
- Changing the air filter
- Changing the fuel filter
- Bleeding the fuel system
- Draining the water separators
- Refilling the urea injection system
You can count on the experts at Circle Automotive to help your diesel engine last a long time.
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 Circle Automotive, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 559-325-9585 or visit Circle Automotive today.
Spark Plug Related FAQs
How do you know when a spark plug needs to be replaced?
The most common sign a spark plug needs replacing is the feeling that the car's engine is hesitating when accelerating, but other signs may include misfiring at start up, rough idling, sluggish acceleration, declining fuel economy and engine knocking.
What else should I replace when replacing spark plugs?
If you are considering having your vehicle's spark plugs replaced, there's a high probability that your spark plug wires need changing as well. Ignition wires become brittle over time. Old ignition wires can break and cause misfires or declining fuel economy.
Serpentine Belt Related FAQs
How do I know if I need to replace my car's serpentine belt?
If your serpentine belt is failing, you may notice performance issues with your vehicle. The vehicle may frequently overheat. Your air conditioning or power steering may fail to work or not work properly. You may notice your vehicle battery failing to recharge if the alternator is affected by a bad serpentine belt. If you start to notice any of these issues we encourage you to bring your vehicle to Circle Automotive as soon as possible to avoid bigger problems and breakdown.
Check Engine Light FAQs
What could cause a check engine light to come on?
Come by Circle 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 simple 50K or 100K mile manufacturer maintenance check.
Is it okay to drive with the engine light on?
The short answer, "No." The longer explanation is the light may indicate a serious engine failure and continuing to use your car as if nothing is wrong could result in a very expensive repair bill. The check engine light means you should stop driving and have your car looked at as soon as possible by a professional at Circle Automotive in Clovis.
What is the most common problem with my check engine light?
A loose gas cap is the most common cause of a check engine light coming on. But the best method to determine why the check engine light is on is to have a professional at Circle Automotive read the diagnostic code in the car's internal OBD computer.
What does a solid check engine light mean?
A steady check engine light indicates a non-emergency issue. Come by Circle Automotive and we can help.
What does an intermittent flashing check engine light mean?
Flashing check engine lights warn of severe situations requiring immediate attention. Get your vehicle to an auto repair shop as quickly as possible or get it safely parked and call a tow truck to take it to your preferred auto repair shop.

Clovis, CA
Blessed to have come upon this shop. My family and I were on a road trip from New York and our car broke down near Clovis at 8pm on Friday. Our Honda Odyssey couldn't take the hilly up and downs of the Cali hills. AAA towed us to this shop but since it was late we would have to wait till the morning to talk to anyone about the work. The shop says it's only open weekdays and Saturday by appt. So we decided we would come in the morning and possibly someone would be there working. We came back the next morning and John was there. He is a very generous and caring man. He decided to look at our car to see what's wrong and ended up helping us out. The day before, we already were thinking the road trip is down and out, and the super old car is dead. Everything was amazing, from the service to the conversations. Huge thank you to John!!
We've gone to Circle Automotive a few times, and each time we received excellent service with a friendly staff.
