Check Your Shocks and Struts at KPS Princeton Garage

Today we're talking to Princeton drivers about shocks and struts. They're so easy for NJ folks to forget about because they last so long and wear out so slowly. But your shocks are really responsible for keeping your tires on the road – so they're very important.

Without shocks, your wheels would be bouncing over bumps and lifting on corners. The shocks push the tire down to the road to maximize traction. Good shocks equal good ride quality and safe handling for Princeton drivers.

There's a difference between shocks and springs. Springs support the weight of the vehicle, keeping it suspended up off the axles. The shocks moderate the rebound motion as wheels hit bumps. Now a strut combines a shock and a coil spring in one compact unit.

It's best to replace all four shocks at the same time. That way you'll have even, predictable handling at all four corners. Anything less could be dangerous.

Visit KPS Princeton Garage to have your shocks and struts inspected by a professional.

Good Service at KPS Princeton Garage Equals Good Fuel Economy in Princeton

Whether we're trying to save money, save gas or save the environment, most of us Princeton drivers have an interest in decreasing fuel consumption. We've all heard about ways to save money on gas in NJ, but does it really add up to much? How much can we boost our fuel economy through preventive maintenance and more courteous driving?

The US government has a website that actually answers that question. Let's look at some of the data and find out if any of these fuel-saving ideas are really worth the effort. We've all heard that a tune-up can improve gas mileage. It turns out that it can save us 4% at the pump. At $3.50 a gallon, that's 14¢ per gallon in savings, and at $4.00 a gallon, that's a 16¢ per gallon savings.

Other common repair items can also save you at the pump. For example, if your oxygen sensor is faulty, it's not delivering the information to your engine's computer that allows it to calculate the right fuel-to-air ratio. The result? The fuel doesn't burn efficiently. Replacing that faulty sensor can save you 40% at the pump. That's certainly a reason to improve your car care and have the automotive professionals at KPS Princeton Garage inspect things once in a while.

A faulty oxygen sensor will activate the check engine light. So will a lot of other problems that are big fuel wasters. Finding out why your light is on and fixing the problem will also improve your fuel economy. Bring your car into KPS Princeton Garage in Princeton and we will take care of it for you.

What about tires? Princeton drivers have all heard that keeping them inflated will improve our gas mileage. True? Yep. It's a 3% savings for that one. And even small drops in tire pressure can start to add up, so a weekly tire check is in order.

Using the correct weight in motor oil is another way you can save at Princeton area gas pumps. It adds up to a 2% savings.

What about that courteous driving? That doesn't cost us anything and doesn't require our Princeton service center to implement anything. Is it worth the bother?

Again, the answer is yes. Sudden acceleration, such as charging away from stoplights, sudden stops and quick lane changes all add up in lowered fuel economy. Taking it easy when you drive on NJ roads amounts to a 5% savings around town and a whopping 33% savings on the freeway. Is it worth your time to slow down? How much do you get paid?

Speeding is another way we ding ourselves at the gas pump. We've all heard that it's okay to drive five miles over the speed limit, but that actually hurts our wallets. Eventually it could add up to more than a speeding ticket. An extra five miles over the speed limit ends up costing us 7% per gallon. Fifteen miles over? 23% Now there's a reason to slow down.

Another thing Princeton vehicle owners can do to improve that costs nothing is to toss the junk out of our trunks. In other words, clean out the car and stop hauling around non-essentials. Don't treat your vehicle like a storage locker. Dumping one hundred pounds of extra weight adds up to a 2% savings at the pump.

So when you tell someone you were going somewhere anyway and they're welcome to come along, that's okay. But if someone tells you they need to come along and it's no harm to you since you were going anyway—well, now you can tell them, “Sorry, dude, but you're an extra fifteen cents a gallon!”

All joking aside, let's all do ourselves a favor and fatten up our wallets by practicing good car care and better driving habits in NJ.

The KPS Princeton Garage Guide to Caring for Your Transmission

Most vehicles have automatic transmissions, yet a lot of Princeton drivers only have a fuzzy understanding about what a transmission does. Think back to the last time you rode a bike in Princeton. You started out in a lower gear and shifted to higher gears as you went faster. Down shift for hills, stuff like that. Think of your legs as the engine – there's an ideal speed you can pedal and you change gears to leverage the work you're doing.

Lower gears for power on hills or for starting out. Higher gears for more speed. That's what the automatic transmission does – it automatically starts in lower gears and shifts up to higher gears to go faster on NJ roads. And it automatically shifts back down to climb Princeton hills, pass or start up again.

Vehicle automatic transmissions have certainly gotten more sophisticated in recent years. They have more speeds than before: the base is four speeds, five is very common.

At KPS Princeton Garage, we routinely service transmissions with six speeds and several have seven or even eight speeds. As you can imagine, this means more parts. Any they all have to fit into roughly the same space.

Transmissions are computer controlled these days, with some high end transmissions having two or three computers. Transmissions are engineered to last. But they are also engineered to tighter tolerances. If a portion of the transmission is starved for lubrication, it can lead to failure.

Not enough fluid can starve the transmission, or dirty transmission fluid can clog small passages in the transmission. Then the lubricant is blocked and can't get to all the parts to protect them, so they wear out prematurely. The technicians at KPS Princeton Garage see far too many transmissions that needlessly failed due to neglect.

And, as you can imagine, repairing one of these new transmissions at any Princeton service center can be quite costly. That's why owner’s manuals have a schedule for how often you should change the fluid and what type of fluid to use.

It's really important for Princeton area drivers to carefully follow the manufacturer's transmission service schedule.

At KPS Princeton Garage in Princeton, we hope you never become shiftless in Princeton because you didn't take care of your transmission.

On Board Diagnostics for Your Engine

Starting in 1996, KPS Princeton Garage service technicians have been able to use a standardized diagnostic system to help determine what is wrong with a vehicle. This diagnostic system works in tandem with the Engine Control Modules for each vehicle's engine. The Engine Control Module is a computer that monitors and controls many engine functions.

Sensors throughout a vehicle send readings to the Engine Control Module. These readings help the computer make adjustments in various vehicle systems to allow for constantly changing driving conditions and even to compensate for minor problems. However, if the computer encounters a situation it can't adjust for, it turns on the Check Engine light. (The Check Engine light is called the “service engine soon” light on some vehicles.)

If the Check Engine light is burning steadily, it indicates a problem that needs to be taken care of soon. If it is flashing, however, the vehicle needs immediate attention at KPS Princeton Garage. When the Check Engine light is flashing, the vehicle should not be driven at high speeds, haul heavy loads or tow a trailer. Princeton drivers need to understand that doing so can cause major damage.

When a vehicle is brought to KPS Princeton Garage in Princeton because the Check Engine light is on, a technician will scan the Engine Control Module to learn why it turned the light on. The answer comes as a “trouble code.” The technician has access to software that allows him to enter the code and find out what it means. The software will also let your KPS Princeton Garage technician know what might be causing the problem and how to diagnose it.

Notice that the trouble code does not tell your technician at KPS Princeton Garage exactly what is wrong with the vehicle. It can only let him know where to start looking to find the problem.

Scanning a trouble code and determining what it means is fairly simple for the pros at KPS Princeton Garage. But the ensuing process of actually diagnosing a vehicle's trouble can take a skilled technician some time. Sometimes this can add up to a significant repair bill. Some vehicle owners mistakenly believe  that the “trouble code” is all they need and think they can then fix their vehicles themselves. Some have tried to save money by purchasing an inexpensive scanner, or they take their vehicles to an auto parts store that offers the scan for little or no cost.

These options are often not the money-savers they seem for Princeton vehicle owners. They can end up costing the vehicle owner extra in unnecessary repairs and engine damage.

For example, the trouble code P0133 reads “Bank 1 sensor 1 circuit slow response.” Translated, that means the front oxygen sensor shows a slow response time in changing the mix of air to fuel. The seemingly obvious conclusion is that the sensor needs to be replaced. The vehicle owner purchases a sensor, installs it and happily goes on his way.

However, read the trouble again: a slow response time in changing the mix of air to fuel. Nowhere does this indicate that the sensor is bad. There are a lot of parts involved in changing the air-fuel mix, any of which could be causing a slow reaction time. Those include a bad or contaminated airflow sensor, an exhaust leak, a problem in the electrical system or a leak in the intake manifold. The sensor is merely relaying that the response time is slow; it doesn't indicate where the trouble is.

So the vehicle ends up with an oxygen sensor it did not need, and the delay in repairing the actual problem may have led to further damage to the engine. Both are added costs for the vehicle owner.

Cheap scanners also don't have the ability to read the history stored in an engine's computer. This operating history contains clues that can help in diagnosing engine trouble since it can indicate a developing problem. KPS Princeton Garage invests a lot of money in high-end diagnostic equipment so that we have access not just to service codes but also to the operating history of the engine.

On-board diagnostics, then, are a tool to help diagnose what is wrong with a vehicle. They cannot specify what part needs to be fixed or replaced, and they cannot replace a well-trained and well-equipped service technician.

Unless you are a trained mechanic, it's good auto advice to use KPS Princeton Garage for your car care. In the long run, it can save you time, unnecessary expense and frustration. KPS Princeton Garage can also help you keep up with your scheduled preventive maintenance, which can also save you on repair bills by alerting you to potential problems before they get expensive.
