Spark plugs, present in all gasoline-powered internal combustion engines, have one very important purpose: to ignite the air/fuel mixture within the combustion chamber to start a car and keep it running. They are also designed to transfer heat away from the combustion chamber to prevent pre-ignition (or igniting the fuel too early). Making sure the … Read more
Picture this: you’re sitting at a stop light on a hot day, getting ready to merge onto the highway. As you pull out and step on the gas, you hear an awful noise that sounds like shaking a bunch of marbles in a can.

While your car doesn’t wear cozy hats, it’s crucial that it constantly monitors the temperature of the engine while it’s on. That’s the job of the engine coolant temperature … Read more
Modern internal combustion engines operate with a precisely tuned balance of air and fuel. Fuel is delivered into the combustion chamber in very specific quantities through components known as fuel injectors. What is a Fuel Injector? A fuel injector is an electronically controlled device which sprays a fine mist of fuel under high pressure. The … Read more
On older engines, distributors are used instead of ignition coils. The distributor cap transfers electricity to the spark plugs through a series of spark plug wires. This entire process happens each time the cylinders of the engine demand a spark to ignite the air and fuel mixture inside of them for combustion. Signs of a … Read more
You go out to your car in the morning to leave for work and see that your door is slightly ajar, which means that the dome light was on all night. You try valiantly to start the car, but when you turn the key nothing happens – the battery is dead. If you’ve ever experienced … Read more
