Light's Out! Trouble Ahead (Exterior Light Bulb Service)

Whether or not your exterior light bulbs are all working probably is not at the top of your list when you think about your vehicle.  But those exterior lights are more important than you think, and they're vital to your safety and that of other drivers near you.

Headlights are important.  Not only do they help you see safely down the road at night, they also help oncoming drivers know that the vehicle they're approaching is not a motorcycle.  Both headlights should be working properly and aimed so that they don't blind other drivers.

Taillights are also important for a few reasons.  They tell drivers what your intentions are (changing lanes, turning, stopping).  So, the bulbs back there must be all in working order for maximum safety. Ditto for the front turn signal lights.  They alert oncoming drivers to your lane changes or turns (if you use your turn signals!).  Some side mirrors also have turn signal bulbs in them.

There are a few other important bulbs.  You may not care about the ones that illuminate your rear license plate, for example. But they are there to help public safety forces identify your vehicle. In fact, in many municipalities you can be pulled over and ticketed if ANY of the standard lights are burned out.  So not only does having all your exterior lights working improve your vehicle's safety, it may keep you from getting a ticket.

Many newer vehicles have a light on the instrument panel that will go on if on-board computers detect voltage problems in any of your vehicle's bulb circuits.  Sometimes it can be hard to figure out which light may be not be working since there are so many. Sometimes it's simply a matter of replacing a bulb, but it may be an electrical problem causing the problem.  Stay legal and safe by having your service repair facility diagnose and fix a non-working light, a really bright idea, don't you think?

Fuel Injection Basics for Farmington

All modern Farmington vehicles come with fuel injection systems, so it's a topic Farmington drivers need to know something about. The mighty fuel injector is a valve that delivers the gas or diesel fuel to the right place, in the right amount at the right time—to be mixed with air and burned in the engine.

So how many fuel injectors does your vehicle have? There's one for each cylinder. So four, six or eight for most folks in Farmington, MI. Some vehicles have 10 or 12 cylinders. The engine control computer makes adjustments to the fuel injector as it monitors the engine and other sensors. Fuel injectors are a pretty high-tech.

Darrell's Firestone can help Farmington drivers with a fuel injector cleaning service. What's the benefit? In order to work right, the fuel injectors have to deliver the fuel at a precise pressure at a very precise time. It's important that the fuel is sprayed in a particular pattern as determined by the engine design.

Over time, varnish can start to build up in the fuel injectors, effecting the pressure, pattern and timing of the fuel charge. The result is that the fuel doesn't get burned as efficiently as it could. That robs performance and hurts fuel economy.

What about dirty fuel? How does that affect the fuel injectors? The fuel injectors are the last stop in the fuel system. It starts at the fuel tank. Frankly, the best way to keep your fuel injectors working well is to use high quality fuel. It's tempting to shop for bargains in Farmington with fuel prices as high as they are, but major brands in the Farmington, MI, area have better detergents and additives and deliver consistent quality.

What about a good fuel filter? The fuel filter is component of the fuel system. Its job is to filter out the dirt and rust that collect in the fuel tank. If it's clogged up, the dirt will bypass the filter and head upstream to the fuel injectors.

It's important to replace the fuel filter when your manufacturer recommends it. That's part of a comprehensive fuel system cleaning.

There are different kinds of fuel injection systems. Port fuel injection systems, the kind most gasoline engines have, operate at 60 pounds per square inch. The injectors for the new gas direct injection engines Farmington drivers are starting to see require 10 to 30 times as much pressure. And some diesel engines for passenger vehicles have injectors that operate at 30,000 pounds or more per square inch. There's no room for dirt and gum in a precision part like that.

There are a lot of good products available in Farmington, MI, that can clean fuel injectors. They're best used to prevent fouling in the fuel injectors. Many can't clean a seriously gummed up injector – that requires a professional deep cleaning, like those we offer at Darrell's Firestone in Farmington. But putting the cleaner in the fuel tank after you've had Darrell's Firestone take a look at your fuel system will help keep it clean. Be sure to read the label for directions.

Give us a call if you think your vehicle may be ready for a fuel injector cleaning.

Idle Talk about Engines (Causes of Rough Engine Idling)

When you slow down at stoplight, your vehicle's idle should be smooth as silk.  But what happens when the engine is missing or idling roughly? That's your engine's way of telling you, "Hey, I've got something wrong with me and if you don't get someone to find out what it is, I may not start the next time you turn the key."

You can help your service facility if you can describe the problem in detail.  Here's a list of things to make a note of:

• When is the problem happening, when the engine is cold or when it's been running for a while?
• Does the rough idling occur when I'm accelerating or when I'm going at a steady speed?
• Does it happen at high speeds?  Does it happen low speeds? Does it happen at both?

Make sure you describe the problem in as much detail because it will help a technician diagnose the problem.

One of the first things they'll check is how the spark plugs are firing.  Modern iridium plugs are supposed to last a long, long time.  But they CAN eventually wear out.  Inspecting the firing end can help the technician figure out the root of the problem.  Corroded or worn out spark plug wires, too, can contribute to an idling irregularity. 

There are other potential problem spots, too.  The technician may check the ignition coil, timing piston rings, valves and cylinder walls. 

If the mixture of air and fuel isn't correct, that may affect how smooth your vehicle is running.  Your service facility is equipped with diagnostic equipment that helps them pinpoint the problem.  Once that idle is smoothed out to the way it used to be, you'll be the smoothest operator on the road.

The Darrell's Firestone Guide to Saving Fuel: Car Weight

The team at Darrell's Firestone in Farmington, and MI car owners are all talking right now. Better gas mileage. Fewer emissions. Farmington drivers want to save the environment and their pocketbooks.

And we all know—or should know—that preventive maintenance will help maximize fuel economy. But is there something more people in Farmington can do? After all, some of us folks can't cut back on our driving, and others would like to do more to economize.

Weight is one major enemy of fuel economy. The more you lug around in your vehicle, the more fuel you have to burn to get from point A to point B. And that means buying more gas in Farmington and producing more emissions.

Of course, your vehicle's weight isn't negotiable. And you can't do much about the weight of your passengers. And this isn't an article about diet and exercise.

But look around your vehicle. Are you hauling a bunch of unnecessary weight around? Do you really need your golf clubs every time you leave your home? Store sports equipment in the garage. Load it when you need it and store it when you don't. Who knows? The extra exercise just might reduce the other type of weight in your vehicle.

The same goes for anything else in your car: make-up kits, music collections, extra electronics, spare clothing; whatever your particular extras may be. Pack it when you need it; store it when you don't.

Clean out your trunk. You'd be surprised how much weight you're lugging around in plain old junk. Toss old papers, leftover food and regular old dirt. Even if it's not a lot of weight, you'll feel better when you get into your car. A good cleaning is also part of good car care.

Now, don't toss stuff you really do need. You do need that spare tire—the one in your trunk. And a kit of emergency essentials is not a bad idea. But just carry around the day-to-day essentials. You can pack a more extensive kit and store it in your garage, then toss it in your vehicle when you go on a longer trip, but you don't have to lug it around all the time. After all, are you a driver? Or are you a junk chauffeur?

Lose the junk and save some money in Farmington.

The Easy Way to Save Cash in Farmington

The hottest MI news story may be different every day, but there's one topic that seems to come up over and over again – the price of gas in Farmington. If you feel like most of your paycheck goes into your gas tank, this post is for you. Here are several basic things people in Farmington can do to greatly reduce their gas consumption, save money, and help the environment. You can really improve your fuel economy by how you drive – but first, here's a review of things you can do for your vehicle that'll save gas no matter how you drive.

The first one for Farmington drivers is keeping tires properly inflated. That can save 2 miles per gallon/.85 km per liter. Driving on low tires is like driving through sand – your car just has to work harder. Most Farmington service centers will fill up your tires for free, so just ask Darrell's Firestone. Also, make a habit of checking your tire pressure whenever you fill up. Many Farmington gas stations have an air hose you can use for free.

Another important item is to keep your air filter clean. An air filter all clogged up with dirt and bugs doesn't let enough clean air through to efficiently burn fuel. Using a dirty air filter will cost you almost 2 miles per gallon/.85 km per liter in reduced fuel economy. And worn spark plugs can cost about the same. A spark plug can fire as many as 3,000,000 times for every 1,000 miles/1,600 km driven. Check the vehicle owner's manual for replacement recommendations.

The biggest item is the oxygen sensor. This device provides the engine management computer with information it needs to fine-tune the fuel/air mix. When that's messed up it can cost Farmington vehicles up to 3 miles per gallon/1.3 km per liter. And of course, there's dirty or substandard oil. Dirty oil causes extra drag. The wrong grade may be too thick. That's another .4 miles per gallon/.17 km per liter right there.

One item Farmington residents seldom think about is their gas cap. A worn, loose or missing gas cap can cost another 2 miles per gallon/.85 km per liter. Adding up all of these worn, missing or sub-par items leads to a total of almost 11.4 miles per gallon/4.85 km per liter in reduced fuel economy! And with current gas prices in the Farmington area, the cost really adds up. Taking care of these simple maintenance items will save Farmington drivers at the pump. 

Now most vehicles aren't missing on all of these items, but think about which ones might affect you right now! And don't forget tune-ups, dragging brakes, low transmission fluid, fuel system cleaning, wheels out of alignment, PCV valve, fuel filter and other services spelled out in your owner's  manual.

Darrell's Firestone knows all this stuff and can tell you when you're scheduled to take care of each item. Create a system of your own to track your service schedules, or just use the computer system at Darrell's Firestone – which may also be updated with recall notices and maintenance schedule items from your vehicle manufacturer.
