When it comes to keeping your vehicle running at peak performance, few systems are as crucial as the fuel injection system. At Classic Import Auto Service in Greensboro, NC, we specialize in diagnosing, maintaining, and repairing fuel injection systems for a wide variety of vehicles—with particular expertise in European models and fine Asian imports, especially Lexus and Acura.
Whether your car is experiencing sluggish acceleration, poor fuel economy, or engine misfires, the problem often lies within the fuel injection system. At our shop, we offer precision diagnostics, factory-grade tools, and decades of experience to ensure your vehicle receives the high-quality service it deserves.
What is the Fuel Injection System?
The fuel injection system is responsible for delivering the right amount of fuel into your vehicle’s engine for combustion. It replaces the older carburetor systems used in older cars, offering greater efficiency, performance, and reliability. This system works by spraying fuel directly into the combustion chamber or intake manifold, ensuring optimal air-fuel mixture ratios for different driving conditions.
Modern fuel injection systems are electronically controlled and require highly accurate calibration. They include several components such as fuel injectors, a fuel pump, sensors, and an engine control unit (ECU). Any failure in these parts can lead to reduced performance and increased emissions.
Why Is the Fuel Injection System So Important?
Your car’s fuel injection system is vital to many performance aspects:
Fuel Efficiency: A properly functioning system ensures your engine uses just the right amount of fuel—no more, no less.
Engine Performance: Smooth acceleration, responsive throttle, and optimal horsepower all depend on clean and efficient fuel injectors.
Emissions Control: A failing system can increase the output of harmful exhaust gases, contributing to environmental pollution and possibly failing emissions tests.
Longevity: Consistent fuel delivery prevents stress on your engine, reducing wear and tear over time.
Ignoring the signs of a failing fuel injection system can lead to more serious and costly engine problems.
Signs Your Fuel Injection System Needs Service
Here are some common symptoms that may indicate your fuel injection system needs professional attention:
Rough Idling or Stalling: If your engine idles unevenly or stalls, dirty or failing fuel injectors may be the culprit.
Poor Acceleration: A clogged injector can disrupt fuel delivery, causing hesitation when you hit the gas.
Increased Fuel Consumption: A malfunctioning injector may spray too much fuel, reducing your miles per gallon.
Check Engine Light: Modern vehicles will alert you through the dashboard if the system isn’t working properly.
Failed Emissions Test: Poor fuel mixture can increase hydrocarbon or carbon monoxide emissions.
Engine Misfires: Inconsistent fuel spray can cause your engine to misfire during operation.
If you notice any of these issues, it’s time to bring your car to Classic Import Auto Service for a professional fuel injection inspection.

At Classic Import Auto Service, we understand the advanced systems in European vehicles and fine Asian imports like Lexus and Acura. Our technicians use OEM-level diagnostic tools and are trained in the specific requirements of these luxury and performance vehicles. Here’s what our fuel injection system service typically involves:
