What Causes Car Misfires?

Engine misfires can be a source of frustration for drivers, leading to decreased performance, rough idling, and even potential damage to the engine. Identifying the underlying causes of vehicle misfires can be just as frustrating. Let's delve into engine misfires, exploring their various causes and offering insights into prevention and troubleshooting. What Are Misfires? Misfires occur when the air-fuel mixture vital to your engine does not properly ignite, disrupting the combustion process. This leads to a noticeable stumble or hesitation in engine performance, often accompanied by vibrations or a loss of power. Ignition systems play a pivotal role in initiating combustion within the cylinders, and any malfunction or disruption can contribute to misfires. Common Causes of Car Engine Misfires Faulty Spark Plugs Spark plugs are appropriately named and are responsible for the "spark" that ignites the air-fuel mixture within the combustion chamber. Over time, spark plugs can wear out or become fouled, inhibiting their ability to generate a vital spark. This can lead to incomplete combustion and subsequent misfires. [...]

Understanding Texas Emissions Testing Texas Emissions Testing is crucial to the state's commitment to environmental conservation. The program aims to reduce air pollution by ensuring that vehicles on Texan roads meet specific emissions standards. The testing process evaluates the emissions produced by a vehicle's engine, focusing on pollutants such as nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC). (This is accomplished by the state and not the inspection station. Whenever a vehicle is being tested, the inspector plugs into the DLC connection and this information is sent to the state at [...]

What is Diesel Exhaust Fluid?

Diesel exhaust fluid (DEF) is a combination of urea and deionized air. This fluid is essential for keeping a diesel engine running smoothly and provides a reduction of harmful contaminants, such as nitrogen oxide, that are released into the environment. When this fluid is allowed to run low, diesel vehicles suffer from reduced performance and may even cease to turn on until the tank is refilled. The Importance of Diesel Exhaust Fluid Diesel exhaust fluid helps to reduce the amount of pollution that is produced by medium and heavy-duty diesel engine exhaust systems. The SCR system injects the DEF into the exhaust, transforming harmful pollutants into clean air through a chemical reaction. DEF is not a fuel additive and it's stored in a separate tank. While it may seem like an inconvenience to spend money on an extra fluid, drivers of diesel trucks, buses, and heavy machinery need DEF to keep their vehicles running smoothly. Do All Diesel Vehicles Require Exhaust Fluid? Vehicle manufacturers began implementing selective catalytic [...]

What’s the Deal With Your Car’s EVAP System?

An EVAP system stands for Evaporative Emission Control System. While most vehicles come equipped with this component, not every driver is aware of its function. These systems have been required on all gas-powered vehicles since the 70s and for an environmentally conscious reason. Before such a system was in place within cars, fuel systems would pollute fumes into the environment even when the engine was turned off. Car EVAP systems are used to keep gasoline vapors contained. This is not only beneficial to the atmosphere but the overall fuel efficiency of the vehicle by keeping the fuel within the vehicle. What Is an EVAP System? These systems are designed around the purpose of preventing gas vapors from seeping out of the fuel tank and into the surrounding environment. This helps control greenhouse emissions. Without a proper EVAP systems in place, gas-powered vehicles would be significantly more environmentally damaging. The EVAP system has been designed to both store and safely dispose of damaging fuel vapors to ensure they aren't released. [...]

Soft Clutch – What Does it Mean?

A soft clutch can be a clear sign that a replacement is in order. As your vehicle's clutch wears down, it may begin to feel soft and spongy when you press down on it. This inconsistent feeling is a sign that you should bring your vehicle into a shop to get it looked at. If your clutch is allowed to break down completely, your car eventually won't move. What Exactly Is a Soft Clutch? For those who have never heard the term, "soft clutch," before, it's simply a reference to a clutch that has been worn down to the point that it feels spongy, or soft, when you put pressure on it. Conversely, if the clutch pedal feels like it’s harder to push down, the pressure plate springs may be getting worn and it’s still a good idea to have a shop look at it. When you depress the clutch, it should have a consistent spring to it all the way down. If you're being met with little resistance [...]

Differences in Wheel Alignment – Front-End and 4-Wheel

If you've been having to fight the pull of your steering wheel while making your daily commute to work, it may be time to head in for an alignment. When a vehicle is out of alignment, drivers may notice that it begins to drift to one side or another — making for unsafe handling on the road. The question is, do you need a front-end or a 4-wheel alignment and what are the differences in wheel alignment? The type of alignment your vehicle requires depends on whether your car or truck has front-wheel or all-wheel drive. After proper alignment has been achieved, you'll have a smoother ride that may even save you money at the gas pump. Front-End Vs. 4-Wheel Alignment and Differences in Wheel Alignment The difference between front-end and 4-wheel alignment comes down to how many tires are being aligned. When a technician aligns all four wheels, it's commonly referred to as a wheel alignment or a 4-wheel alignment. If only two wheels are needing to be [...]

Is it the Battery, Starter, or Alternator?

When you've got places to be, but a car that won't budge, it leads to some strong feelings of frustration — and confusion! Your next question is probably, "is it the battery, starter, or alternator?" With all three having the ability to cause your engine not to start, 1/3 isn't seeming like good odds anymore. A little knowledge can go a long way in helping you diagnose the issue (and how much effort it will be to get your car going again). Car Parts 101 - The Battery, The Starter, and The Alternator While the three parts work in tandem to get your car moving, they all have separate (but equally important) roles. Car Battery Your vehicle's battery is the first spark that ignites the engine into action. Once the ignition switch is engaged (either by turning the key or pressing the start button), the battery sends voltage to the starter to help it get the gears turning. It also lets you crank the tunes without having your car [...]

I Put the Wrong Fuel in My Car – Now What?

We've gone over the different fuel types in previous articles. Whether from not knowing any better or an accident, putting the wrong fuel into your vehicle can cause some issues. If you mitigate this mistake quickly enough, you can minimize the damage. Put the Wrong Fuel in Your Car? Here's What to Do. The first step: quit driving and look up what you need to do (see below). The less fuel that is entered into your system, the better. From there, here's what you need to do to know about the wrong gas types. Gas in Diesel Vehicles Diesel and Gas are very different fuel types. Diesel fuel is thicker and acts as a lubricant. Thinner gasoline fuel causes wear to the fuel pump, injectors, and filters. This wear can happen quickly. Immediately halt your travels and call a tow truck for a ride to your local automotive shop, where they can drain the tank and fuel lines and fuel filter/s. Diesel in Gas Fueled Cars While engine damage [...]

Diesel vs. Gasoline

We all know that gasoline and diesel fuels are different. We know not to put diesel into a gas engine and vice versa. But, do we know the "whys" behind that rule? When it comes to diesel vs. gasoline, not only are the fuel types different, but the respective engine types are different. And each fuel engine comes with its benefits as well as disadvantages. Diesel vs. Gasoline Gasoline engines were invented in 1876 and were ground-breaking — but they weren't efficient. The four-stroke combustion engine only utilized 10% for the fuel, while the other 90% produced heat and burned off. So, in 1892, Rudolf Diesel created the combustion power engine (also known as the diesel engine). While gasoline engines have had many technological advances that led them to be more efficient than the original model, they operate slightly differently from their diesel engine counterparts. Diesel and Gasoline Engine Differences Both engines use internal combustion, with cylinders compressing air and fuel mixtures to create mechanical energy turned into motion [...]
