What You'll Learn
Fuel injector cleaning services
Fuel injectors are designed to last for well over 250,000 miles. However, over time, harmful deposits can build up inside and around the injectors' nozzles, clogging the injectors' internal microfilters and disrupting the fuel injectors' spray pattern and atomization. This can cause issues with combustion in the cylinder, leading to reduced performance and other drivability issues.
There are a few things you can do at home to determine if your fuel injector is malfunctioning or simply dirty. You can start by unplugging the electrical connector for each injector one at a time and applying a multimeter to the contact points to check for normal function. If you detect normal function, your fuel injectors are likely just dirty, and you can try using a product like Rislone Fuel System Treatment to cure your fuel injector problems.
If you are still experiencing issues, you may need to send your fuel injectors to a professional cleaning service. Several companies offer fuel injector cleaning and flow testing services, including:
- Fuel Injector Clinic: This company offers ultrasonic cleaning and flow testing services for top-feed fuel port injectors only. The process involves filling out a one-page form and sending in your injectors for cleaning and testing. The cost is $25.00 per injector.
- Injector Rx: This company offers cost-effective fuel injector cleaning and flow testing services for a variety of industries, including automotive, motorcycle, and marine. The cost starts at $22.00 per manifold injector or $30.00 per direct injector, and the turnaround time is typically 3-4 business days for standard service and 1 business day for expedited service.
- Fuel Injector Repair LLC: This company offers ultrasonic fuel injector cleaning and flow testing services for most automotive, truck, marine, motorcycle, ATV, and snowmobile gasoline fuel injectors. The cost is $17 per injector, and the servicing process typically takes 1 to 4 days.
It is important to note that not all fuel injectors can be cleaned and restored to like-new condition. In some cases, injectors may fail a resistance or reluctance test, indicating an electrical issue that cannot be repaired. It is always recommended to consult with a professional service to diagnose and address any issues with your fuel injectors.

Rebuilding fuel injectors
Fuel injectors are designed to last for well over 250,000 miles. However, over time, harmful deposits can build up inside and around the injectors' nozzles, causing clogging and disrupting the fuel injectors' spray pattern. This can lead to issues with atomization and distribution, resulting in uneven and incomplete combustion in the cylinder.
Before deciding to rebuild your fuel injectors, it is important to determine whether they are malfunctioning or simply dirty. You can do this by unplugging the electrical connector for each injector and applying a multimeter to the contact points to check the resistance. If the injectors show normal function, they may just need cleaning.
There are several companies that offer fuel injector cleaning and flow testing services, such as Injector Rx and Fuel Injector Repair LLC. These services typically use an ultrasonic cleaning method to remove dirt, carbon buildup, and other deposits from the injectors. The cost of these services can vary, but they are generally much cheaper than purchasing new or refurbished fuel injectors.
Alternatively, you may consider rebuilding your own fuel injectors. This can be a more cost-effective option, but it requires a clean work area and the right tools, such as a small ultrasonic bath. It is important to note that fuel injectors have very small orifices, and even a small amount of dust or debris can cause issues.
Overall, whether you decide to rebuild your own fuel injectors or send them to a specialist, it is important to address any issues promptly to ensure optimal performance and fuel economy.

Signs of a faulty fuel injector
Fuel injectors are designed to last for well over 250,000 miles, but over time, harmful deposits can build up inside and around the injectors' nozzles, causing issues. There are several signs that your fuel injectors may be faulty or dirty and in need of a clean, repair, or replacement:
- Poor performance and decreased mileage: If your engine is starved of fuel, it will rapidly lose power. You may find it hard to accelerate or your engine might struggle with uphill stretches of road.
- Engine stumbling and misfiring: A fuel-air mixture inside the combustion chamber of each cylinder is usually finely balanced. When insufficient fuel is injected, that balance is lost and the cylinder starts misfiring, causing the engine to stutter and judder as it misses revolutions.
- Rough idling: This is typically characterised by varying RPMs, even when your foot is off the gas pedal. Rough idling can be accompanied by engine stalling, which is a sudden stop in RPMs and engine noise that feels like running out of gas on a hill.
- Unusual tachometer readings: The needle on the tachometer (RPM gauge) may move unprompted, indicating changes in RPM when your car isn't switching gears.
- Check engine light: The check engine light on your dashboard may flash or illuminate, indicating a problem with the fuel injector.
- Fuel leaks: A fuel leak could be a sign that there is a crack in the rubber seals or in the fuel injector itself.
If you suspect your fuel injectors are faulty, it is important to get them checked by a professional. Several companies offer fuel injector cleaning and testing services, including Injector Rx and Fuel Injector Repair LLC.

Replacement fuel injectors
If you are experiencing issues with your fuel injectors, there are a few things you can do to determine whether they need to be replaced or simply cleaned. A common issue with fuel injectors is clogging due to dirt and carbon buildup, which can usually be fixed with a simple application of a fuel system treatment product such as Rislone.
If you suspect that your fuel injectors are clogged, you can perform a simple test by unplugging the electrical connector for each injector with the engine off and applying a multimeter to the contact points. By checking the service manual or online sources, you can determine the correct resistance (typically between 10 and 18 ohms). If the injectors show normal function, it is likely that they are simply dirty, and regular use of fuel system treatment products can help keep them clean.
However, if your fuel injectors are beyond repair, you may need to replace them. Replacement fuel injectors can be purchased from automotive stores such as AutoZone, which offers a wide range of fuel injectors for various makes and models, including Honda Civic. It is recommended to consult a professional for the replacement process, especially if you are unsure about doing it yourself.
Alternatively, you can send your fuel injectors to a specialist service such as Injector Rx for cleaning, flow testing, and rebuilding. They offer cost-effective services and guarantee results, servicing fuel injectors for various industries at a fraction of the cost of new or refurbished injectors. The standard turnaround time is 3-4 business days, but they also offer expedited services.
If you choose to replace your fuel injectors yourself, it is important to take safety precautions. Always wear protective gear, including gloves and eye protection, and have a fire extinguisher nearby when working on the fuel system. Additionally, make sure to relieve the fuel pressure before disconnecting any components to prevent unexpected fuel spray.
