Millington Customer Detective Work

One might say the most challenging part of being an automotive service technician at Long Hill Auto Service is diagnosing a problem before it can be fixed.

Cars are made up of a bunch of complex systems. There usually could be a number of reasons for any given symptom. So, it's challenging to track down the actual cause of the problem. And it can be frustrating for the vehicle owner because it can take time and money to get to the bottom of a problem. If it's not something obvious, it's easy for the customer to focus on the fixing and not the diagnosing.

Let us at Long Hill Auto Service introduce you to something we'll call 'Customer Detective Work' –  helping your technician find clues to what's wrong.

We start with the detective basics: What, Where and When. Play along with me; You come in to Long Hill Auto Service and your car is making a funny sound...

• Q: Where's the sound?
• A: Around the right front wheel.

• Q: What kind of sound?
• A: Kind of a clunk, clunk sound.

• Q: When do you hear the sound?
• A: When I turn and accelerate. 

• Q: Right and left? Forward and back?

Do you see where we're going? You're gathering additional information to help your technician at Long Hill Auto Service know where to start. Based on your car and the tech's experience, he'll know where to look and can start with the obvious suspects.

You can see how that would be more helpful than dropping the car off with a note that says "making a funny noise."

If the tech can experience the problem personally, he's better able to make a diagnosis and repair and then test to see if the repair solved the problem.

Restore Your Get-Up-and-Go (Fuel and Air Induction Cleaning)

You may have heard the old saying, "My get-up-and-go got up and went." If your vehicle's engine's fuel economy is noticeably worse, your engine is idling roughly or stalling or your vehicle's acceleration isn't what it used to be, ask your service advisor if you might need your vehicle's fuel and air induction systems cleaned.

As the hours pile up on your engine, carbon deposits can build up.  It's not unusual for some of the impurities and additives in fuel to leave behind a black residue that eventually will negatively affect your fuel economy and performance. Maybe you're noticing your engine is harder to start, you hear knocking or pinging in your engine and your vehicle just doesn't have the pep it used to.

While it's a sophisticated process with a lot of components, a gasoline engine essentially produces power by drawing in air from the outside and mixing it with fuel in the cylinders where this blend of fuel and air is ignited by spark plugs in synchronized explosions.

The fuel and air enter your engine through the fuel induction system and air induction system. Because of things like high operating temperatures and impurities, carbon in the fuel can leave behind dark, sooty deposits in the fuel induction system such as the fuel injectors and the throttle body. These and other residue reduce your engine's efficiency and performance. Our service center can use special fuel injector cleaners to remove those deposits from your engine.

The technician may manually clean some of the deposits and also put a fuel additive in the fuel tank that will get rid of other deposits that are still in the fuel system

Keeping the air induction system clean is also important.  A technician can use a liquid cleaner specially designed for the job. Not only can this improve your fuel economy, it may also reduce exhaust emissions and help your engine last longer.

Most gasoline now contains detergents that help reduce or prevent these problems, but direct injection is now being used in more vehicles that are more susceptible to clogging. Ask your service advisor if your vehicle could benefit from fuel and air induction cleaning.

Weather Station on Wheels (Vehicle Sensor Maintenance)

You probably never thought about it, but your vehicle is like a rolling weather station.  It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool.

First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in.  Some of those sensors can control computerized systems in your vehicle to react to the weather.  It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle how those sensors will respond.

Let's start with temperature.  Most vehicles now have a thermometer that measures the temperature outside.  It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures.  But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning.  If your ambient temperature sensor isn't working right, some symptoms are a malfunctioning automatic A/C or a temperature display that is way different than the app on your phone says it should be.

Your vehicle will also have sensors that measure your speed at each wheel.  They work with an onboard computer to measure slippage in any of the wheels so traction control and antilock brakes work correctly in case of slick roads.

Your vehicle can measure something called longitudinal and latitudinal acceleration, and it uses a yaw sensor to do it.  That helps it determine if you might be in an oversteering or understeering situation.  It's important because it works with your vehicle's brakes to apply stopping power to keep you in control.

A steering wheel sensor tells the vehicle's computers what the driver is doing with the wheel.  It also can work with those wheel sensors to measure how slippery the roads are, whether it be due to a wet (rain) or granular (gravel or sand) surface.  By sending different torque or braking to each wheel, it helps the driver maintain control.

More and more vehicles now have a rain sensor that can turn on the wipers automatically when they measure precipitation on the windshield.

So, you're driving your own weather station, and making sure all this data is coming in properly depends on how each component is working.  Regular service and maintenance on these systems is important to make sure they can do their job. Your rolling weather station can't predict the weather, but it can sure help you deal with it, so help it do its job right.

Direct Fuel Injection Update from Long Hill Auto Service

For those of you in Millington, NJ who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.

For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same fuel economy. The turbocharged version makes over 350 horsepower.

So what are the differences from a conventional engine?

The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it's then drawn into the engine with the air.

With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder during the combustion cycle is burned much more efficiently.

First, the fuel is squirted in at hundreds of times more pressure, so it's atomized much better and burns cleaner and stronger. The other big advance is in electronics. Faster engine management computers can control the additional precision required to manage direct fuel injection.

Fuel injectors are precision instruments. They have to deliver a precise amount of fuel at exactly the right time. The design of the engine also dictates a particular spray pattern for the fuel. If a fuel injector is dirty or gummed up, it can't do its job as well. That means less power and worse fuel economy for your vehicle and can lead to damaged fuel injectors.

Replacing fuel injectors at Long Hill Auto Service isn't cheap. Direct injection injectors are even more expensive because of the extremely high-pressure they use. Same thing for diesel fuel injectors; we're talking mortgage payment-range to replace a set of diesel injectors.

A professional fuel system cleaning from Long Hill Auto Service gets out the gum and varnish in the whole system, including the fuel injectors. Keep those injectors clean and they'll last a long, long time.
