Engine Repair & Maintenance in Princeton
Your engine is one of, if not the most important component of your car. Without it working in proper order, it's impossible for you to go anywhere. If it runs inefficiently, you may face a whole host of problems that can be avoided with relatively simple maintenance. At KPS Princeton Garage we provide all of the expertise and parts needed to keep your engine running happily and at peak efficiency.
Engine Maintenance Service We Offer
Below are the services we can perform to ensure your engine remains healthy:
Check Engine Light
No one likes to see their car's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. At KPS Princeton Garage, we can pull the code and diagnose the problem for you. Give us a call at 732-297-9515 or stop by the shop for our expert assistance.
Fuel Injection
Fuel injection is a system for admitting fuel into an engine. Since 1990, fuel injectors have completely replaced carburetors as the primary means of getting gasoline into the engine. A fuel injector atomizes the fuel by forcibly pumping it through a small nozzle (under high pressure). Failure of the fuel injection system means poor performance and ultimately destroys the engine.
Ignition
Your vehicle's ignition system is responsible for starting the engine by delivering an electrical spark that ignites the air-fuel mixture in the combustion chamber. Issues can involve a worn ignition switch, a faulty ignition coil or broken or corroded wiring. These problems can lead to symptoms like the engine failing to start, intermittent stalling, dashboard warning lights, or even complete power loss while driving.
Ignition Wires & Cables
These vital parts transfer the spark from the ignition coil to spark plugs that ignite the mixture of fuel and air. The mixture starts the engine. Over time, ignition wires and cables get weak and break down. This makes it impossible for the spark to reach the engine cylinders. This results in the engine misfiring. Common symptoms of faulty ignition cables and wires are: poor gas mileage, engine misfires, engine light is on, and engine vibration.
Oil, Lube, and Filter
To keep running smoothly, your car highly relies on oil, lube, and oil filters. Oil helps in lubricating, cooling, and cleaning the internal engine components. With time, motor oil becomes contaminated. Your car needs an oil, lube, and filter change every three months (or 3,000 miles) in order to function optimally.
Spark Plugs
A spark plug delivers electric current to the combustion chamber from the ignition system. Spark plugs that haven't been changed for a long time can cause ignition problems. At KPS Princeton Garage, we have automotive experts who will check and replace your spark plugs. For all your spark plug repair or replacement needs, call 732-297-9515 or visit KPS Princeton Garage today.

Check Engine Light FAQs
Is it okay to drive with the engine light on?
The short answer is "No." The longer explanation is that the light may indicate a serious engine failure, and continuing to use your car as if nothing is wrong could result in a very expensive repair bill. The check engine light means you should stop driving and have your car looked at as soon as possible by a professional at KPS Princeton Garage in Princeton.
What could cause a check engine light to come on?
Come by KPS Princeton Garage and we can diagnose the reasons for a check engine light turning on. It can range from something serious like a faulty catalytic converter or potential engine failure to something simple like a loose gas cap or the need for a simple 50K or 100K mile manufacturer maintenance check.
What is the most common problem with my check engine light?
A loose gas cap is the most common cause of a check engine light coming on. But the best method to determine why the check engine light is on is to have a professional at KPS Princeton Garage read the diagnostic code in the car's internal OBD computer.
What does an intermittent flashing check engine light mean?
Flashing check engine lights warn of severe situations requiring immediate attention. Get your vehicle to an auto repair shop as quickly as possible or get it safely parked and call a tow truck to take it to your preferred auto repair shop.
What does a solid check engine light mean?
A steady check engine light indicates a non-emergency issue. Come by KPS Princeton Garage and we can help.
Spark Plug FAQs
How do you know when a spark plug needs to be replaced?
The most common sign that a spark plug needs replacing is an engine that hesitates during acceleration. Other warning signs may include engine misfires during startup, rough idling, sluggish acceleration, declining fuel economy, and engine knocking.
What else should I replace when replacing spark plugs?
If you're considering having your vehicle's spark plugs replaced, there's a good chance the spark plug wires should be replaced as well. Ignition wires become brittle over time, and worn wires can lead to engine misfires, poor performance, and reduced fuel economy.
