Check Engine Light Diagnosis at McPherson Automotive

Hello Du Quoin . Have you ever had your Check Engine light come on? Did you panic? Or just scowl and ignore it? What should you do? Pull to the side of the road and call a tow truck? Or just keep driving? What does that little light really mean for Du Quoin drivers?

First of all, the Check Engine or Service Engine light does indicate that something is wrong. That's why it is called a warning light. But the something that is wrong might be a loose gas cap, or it might be serious vehicle engine trouble. That's why Du Quoin residents often don't know how to respond to it.

The Check Engine light has two modes: it flashes or it stays on. A flashing light is serious. You need to get your vehicle to McPherson Automotive in Du Quoin ASAP. No, you don't need to call a tow truck, but, yes, you can't wait to get your car serviced. If your Check Engine light is on and flashing, you should not tow trailers, haul heavy loads or drive at IL freeway speeds. Any of these could lead to serious damage that could result in repair bills for Du Quoin drivers who ignore it.

A steady Check Engine light is less serious, but that doesn't mean it can be ignored. You should plan to get your vehicle inspected at your local Du Quoin automotive service center at the first realistic opportunity. Not the first convenient opportunity, but the first realistic one.

Modern automobiles have a computer in the engine that monitors and controls many of the engine functions. When the computer senses something wrong, it first tries to fix the problem itself by adjusting the vehicle engine. If the problem persists, the computer signals the Check Engine light to come on.

This process stores a trouble code inside the vehicle engine's computer. Your service advisor at McPherson Automotive scans the computer and reads the code. This does not tell the technician exactly what is wrong with the car, but it gives him a good idea as to where to start looking.

Of course, the best thing to do is to keep that pesky Check Engine light from coming on in the first place. Good vehicle care and routine preventive maintenance go a long way to keeping your vehicle out of your Du Quoin auto repair shop. But, if that light does come on, be smart. Take care of the problem early, and take care of it professionally.

Tire Maintenance in Du Quoin

With the recent focus in the Du Quoin area on improving fuel economy, we've been told how important it is to maintain our tire pressure.

Du Quoin drivers know that tires wear out, but we want to make them last as long as possible because they're not cheap to replace. In addition to saving gas, properly inflated tires last longer. Underinflated tires will wear out more quickly.

Some people in Du Quoin wonder if they should add a few extra pounds of pressure when they fill up their tires. Bad idea. In fact, there are very good reasons not to overinflate your tires. For one, the middle of the tread will wear unevenly because the full tread is not contacting the road properly. That also adversely affects your handling.

Stop by McPherson Automotive to see about tire maintenance for your vehicle.

Every vehicle in the Du Quoin area has a sticker on the driver's side door jamb that tells you the vehicle manufacture's recommended tire pressure. This recommendation is an integral part of the vehicle's suspension tuning. A lot of engineering actually goes into the recommended tire pressure, so it's important for drivers to follow it.

What else do Du Quoin drivers need to know about tire maintenance? Tire rotation and balancing are very important. Let's start with rotation. Because the front tires handle the brunt of turning forces, the shoulders of the front tires wear more quickly than the rear tires. At McPherson Automotive in Du Quoin, we rotate the tires so that they all get to do some duty on the front, and they'll all wear evenly over their live.

For most vehicles, front tires are rotated to the rear and vice versa. Others recommend a cross rotational pattern. Some vehicles use an asymmetrical tire so those tires need to stay on either the right or left side – it'll say which on the tire. Some high performance cars have asymmetrical tires and different sizes on the front and rear. These can't be rotated at all. Your owner's manual will have details for your vehicle or ask your service advisor at McPherson Automotive.

How often should people near Du Quoin rotate their tires? Your owner's manual will have a recommendation. Your technician at McPherson Automotive in Du Quoin can do a visual inspection to let you know if it looks like it should be done. The interval is typically around 5,000 miles/8,000 km.

You know, some people don't think new tires need to be balanced. What they aren't taking into account is the wheel. Between the wheel and the tire – even a new tire – there's enough variation to require balancing.

When you add the valve stem and tire pressure monitoring sensors required on new cars, balancing is definitely important. When a tire's out of balance, it's actually hopping down the road. Du Quoin vehicles with tires out of balance will feel the vibration through the steering wheel if a front tire's out of balance and through the seat if it's a rear tire.

Proper wheel balance promotes tire life and increases safety for Du Quoin drivers and their passengers. Historically, lead weights have been attached to the wheel to bring it into balance. Lead gives some environmental concern, so steel weights are starting to be substituted. 

The team at McPherson Automotive also wants to remind you that it is important to always use the same size tire on an axle. Different size tires on the front or on the back can lead to some real handling problems. And tire manufacturers recommend that when you get two new tires, they be installed on the rear because that's where you need the most traction to avoid spinning out.

Fuel System Cleaning at McPherson Automotive in Du Quoin for Better Performance

A fuel injector is a valve that delivers fuel to a vehicle's engine. It has to deliver the precise amount of fuel to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.

Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.

The pressure in a fuel injection system varies depending on its type. Many gasoline engines use port injection systems, which operate with a pressure of 60 pounds per square inch. Newer direct injection systems operate at 10 to 30 times that pressure. Some diesel passenger vehicles have fuel injectors that operate at 30,000 pounds or more per square inch.

Vehicles have one fuel injector for each cylinder in the engine. Your vehicle's control computer constantly monitors the engine and various sensors in the vehicle.  It also adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle's engine.

Because fuel injectors are such precision instruments, dirt and contaminants are a serious detriment to their performance. When an injector gets gummed up, it affects the pressure, pattern and timing of the fuel delivery. The result is a decrease in fuel economy and loss of engine performance.

So it's important to keep your fuel injectors clean. That starts with keeping the fuel in your tank clean. High-quality fuel contains detergents and additives that help clean your engine. Brand-name IL fuel companies also deliver a more consistent quality of fuel than do bargain stations in the Du Quoin area.

The second way to keep your injectors clean is to keep your fuel filter clean. This filter screens dirt and rust out of the fuel as it travels from the tank to the engine. If the filter clogs up, fuel will bypass it and carry its load of dirt into the engine.

Check your owner's manual or ask the pros at McPherson Automotive in Du Quoin to find out how often you should change your fuel filter. This should be part of your regular preventive maintenance. Also, remember that if you use bargain-brand or low-grade fuels, or if you drive an older vehicle, your filter will need to be changed more often.

You can also purchase cleaners that will protect your fuel injectors. These cleaners are added to the fuel tank. They work best at preventing build-up in your fuel injectors and can clean up small amounts of carbon, gum and varnish. But they won't be able to clean a fully gummed-up injector. Read the labels before using any of these products for full directions on their use.

If your fuel injectors are gummed up, you can get a professional deep cleaning service at McPherson Automotive in Du Quoin that will result in better fuel economy and improved vehicle performance.

Good vehicle care will prevent serious damage to your fuel injector system. And this is one system that you want to keep in perfect condition.

Distracted Driving

When asked, most people think they are good at multi-tasking. Scientific studies, however, reveal that only around 2% of the population can truly demonstrate the capacity to effectively multi-task. For the rest of us who are not so biologically wired, no amount of practice can increase our effectiveness at multi-tasking. Turns out, multi-tasking is almost a superpower. Think of fighter pilots: capable of maintaining their orientation in three dimensional space and performing specific and highly complicated functions while accessing life threatening situations and coming up with an appropriate response. Admit it – you can’t do that.

Yet when it comes to driving, we seem to think we are very capable of safely operating a motor vehicle with myriad distractions. 77% of young adults feel somewhat confident that they can safely text and drive while 55% claim it’s easy to text and drive. Can they possibly be right? Let’s look at some statistics.

Nearly 23% of all accidents in the United States involve cell phones. Every day, 11 people are killed and over 900 are injured in texting-related accidents. In fact, texting while driving is six times more likely to cause an accident than driving intoxicated. Just think back at your own experiences: how many of your “near misses” as a pedestrian or in a vehicle have involved a driver with a cell phone in their hand?

There are three types of driving distractions:

• Visual (eyes off the road)
• Manual (reaching for something or manipulating an object)
• Cognitive (mind off the task of driving)

Of course, texting or using a cell phone involves all three. Eating, applying make-up, arguing and working on-board features like the stereo and navigation system are all very real distractions. You may be interested to know that hands-free cell calls are not substantially safer than using a handheld phone. Any time you glance away from the road (like looking at a text or incoming phone call) your eyes are off task for at least 5 seconds. At 55 miles per hour/90 kph, you will cover the length of a football field in that time. Would you ever consent to strapping on a blindfold and driving off down the road for that distance?

So what do you do? First, accept the fact that you are not part of the 2% of all the people on the planet who can truly multi-task (if you are one of the lucky ones you would know by now because your performance does not degrade no matter how many additional tasks are added). Next, don’t EVER drive distracted. Incoming text: it will wait for later. Juicy hamburger: eat it in the parking lot. No exceptions, ever. And don’t accept anything less from drivers of vehicles in which you are a passenger.

Another way to avoid distractions is to keep on top of scheduled maintenance and necessary repairs so that your vehicle itself doesn’t become a distraction. We can help you with that.
