Fuel Injector Types and Prices

Fuel injectors are designed to last for the entire lifespan of a vehicle. However, fuel contamination and carbon buildup in the engine can cause clogging or cracking. It is recommended that fuel injectors are cleaned every 40,000 miles or 3 years, or every 40,000-60,000 kilometres.

There are a variety of fuel injectors available for the GMC Acadia. Fuel injector prices vary depending on the manufacturer and the type of injector. For example, remanufactured fuel injectors are cheaper than new ones, and some injectors are designed for specific engine types.

Remanufactured fuel injectors from CARQUEST, for example, are available for the GMC Acadia for as little as $54.99. These injectors are remanufactured using a 15-step process in the USA and are 100% tested under multiple operating conditions.

The price of a fuel injector depends on the brand, the type of injector, and the vehicle it is designed for. It is important to consider the quality and compatibility of the injector when making a purchase decision.

Fuel Injector Cleaning

When to Clean Your Fuel Injectors

It is recommended to clean your fuel injectors about once a year. This can help prevent the buildup of harmful deposits. If you clean less regularly, carbonaceous deposits can grow and harden, hindering the function of your vehicle. If you do not use your vehicle often, you can clean the fuel injectors every 15,000 miles instead.

If your vehicle is in good condition and the fuel quality is good, you can also consider cleaning your fuel injectors every 40,000-60,000 kilometers. Even if your fuel injection nozzle is slightly clogged, you don't need to worry. The impurities can be sprayed and dissolved when accelerating at high gear.

Steps to Clean Your Fuel Injectors

• Purchase a fuel injector cleaning kit: Look for a cleaning kit that is suitable for your type of vehicle. Each kit should come with a canister of fuel injector cleaner and a hose that attaches to the fuel injector and fuel rail. For the best results, opt for a cleaning fluid that contains polyetheramine (PEA), which will dissolve thick carbon deposits effectively. Most fuel injector cleaning kits can be used for any type of vehicle, but you should always read the package or ask a store clerk to make sure.
• Locate the fuel injectors: Different types of engines have different layouts, so your fuel injectors may be difficult to find. Take a look at your vehicle's manual to determine where the fuel injectors are located. They will be located under the hood of the car.
• Disconnect the fuel pump from the fuel injectors: Brace the fuel pump, which should be located on the side of the engine. Gently pull out the fuel injectors to detach them from the pump. Once they are removed, connect the fuel return line to the fuel pump so that the gas inside it returns to the tank while you're cleaning the injectors.
• Disconnect the pressure regulator vacuum line: If your vehicle has a fuel pressure regulator, locate it and look for the vacuum line attached to it. Gently pull out the vacuum line to disconnect it.
• Connect the cleaning kit to the fuel port: Follow the detailed directions provided with your cleaning kit on how to attach the hose and fitting to the fuel port. This will vary depending on the kit, but ensure that the fitting is attached properly to both the hose and the port. Make sure the injectors have no exposure to fuel as the cleaner is flammable.
• Remove the cap from the fuel tank: Before starting the cleaning, remove the fuel tank cap to prevent excessive pressure buildup, which could lead to combustion.
• Turn on the vehicle to let the cleaning fluid into the injectors: Double-check that your fuel pump is turned off. Start your engine and let it run. The motor will stop running once the cleaning fluid is all used up, which usually takes 5 to 10 minutes.
• Remove the cleaning kit and reattach your pump and injectors: After the cleaning fluid has been used up, remove the hose and fittings from the fuel port. Reattach the fuel pump power supply and the pressure regulator vacuum hose. Put the fuel cap back into place.
• Test the fuel injectors: Turn on the vehicle again to make sure the fuel injectors are working properly. Listen for any abnormal noises, which may indicate a problem. Drive the vehicle a short distance to ensure it runs smoothly.

Additional Tips:

• Keep a fire extinguisher nearby as a safety precaution during the cleaning process.
• Avoid getting any cleaning fluid on the outside of the vehicle, as it may damage the paint.
• If you are unable to perform the cleaning yourself, consider taking your vehicle to a professional mechanic for a fuel injector cleaning service.

Symptoms of Bad Fuel Injectors

The fuel injectors in your 2010 GMC Acadia play a critical role in delivering fuel to your engine. When they malfunction, it can cause a range of issues that impact performance and fuel efficiency. Here are some common symptoms of faulty fuel injectors:

Engine Misfires and Stumble

A cylinder that is starved of fuel due to a faulty injector will not generate sufficient power. This can cause the engine to misfire and stutter, with the engine missing revolutions. You may also experience engine hesitation or stumble, where the engine runs unevenly and RPMs fluctuate.

Rough Idle

When your vehicle is idling, a faulty injector can make the engine sputter and shake, especially when not under throttle. This is often characterised by varying RPMs even when your foot is off the gas pedal.

Poor Fuel Economy

A fuel injector that is stuck open can dump excess fuel into the cylinder, leading to increased fuel consumption. Even if the injector is not stuck open, fuel economy can still decrease as the engine compensates for a poorly operating cylinder.

Engine Surge During Acceleration

Inconsistent injector performance can cause occasional surges in engine power. This is due to the injector spraying the correct amount of fuel at one moment, and then too much or too little the next.

Check Engine Light

The check engine light on your dashboard may illuminate, indicating a range of issues, including a faulty fuel injector. This can be caused by the injector supplying too little or too much fuel to the engine, resulting in decreased engine performance and fuel economy.

Black Smoke from Exhaust

A malfunctioning injector can leak too much fuel into the combustion chamber, creating an overly rich fuel-air mixture. This excess unburned fuel can flow back into the exhaust system and escape from the tailpipe as black smoke.

Fuel Leak

Over time, heat and moisture can take a toll on the fuel injector, causing cracks in the rubber seals or the injector itself. This can result in a fuel leak.

If you notice any of these symptoms, it is important to have your vehicle inspected by a qualified technician to diagnose and address any issues with your fuel injectors.
