What You'll Learn
Using professional cleaning services
If you're looking to professionally clean the fuel injectors of your 2007 Ford Mustang, there are a few options available to you.
Firstly, you can call around to various shops and automotive machine shops in your area to find one that has an injector cleaner/test stand. This option will not only ensure your injectors are properly cleaned, but it will also help identify any injectors that are not functioning optimally. The typical cost for this service is around $17 per injector, but prices can vary depending on the shop and their overhead. Some shops may charge as little as $5 per injector, while others may charge closer to $100.
Another option is to send your injectors away to a professional cleaning service. This option typically costs around $150-$200, and you will get your own injectors back, which may be preferable to purchasing remanufactured injectors of unknown mileage.
When deciding between cleaning and replacing your fuel injectors, it's worth considering the cost of replacement injectors. Remanufactured injectors typically cost around $25-$35 each, while new injectors can cost upwards of $45 each.
In terms of the cleaning process itself, a professional service will typically use a kit that includes a canister with fuel and a detergent. They will disable your fuel pump and connect the kit to the fuel rail, running it until the canister is empty. This is considered the best way to truly clean your fuel injectors.
Some professional services may also offer flow testing as part of their cleaning package, which can help ensure your injectors are functioning optimally and identify any potential issues.
It's worth noting that while some people opt for at-home cleaning solutions or additives, these may not be as effective as a professional cleaning service. Additionally, some products can be harsh and may damage certain components of your car, so it's always best to consult a professional before attempting any cleaning or maintenance on your fuel injectors.

Flow testing
External Cleaning and Inspection:
First, the fuel injectors are externally cleaned with a special detergent to remove any dust or grease. This step is crucial as it ensures that the injectors are ready for the detailed inspection process.
Coil Testing:
The injectors' coils are then tested for resistance, shorts, and current draw. This includes a resistance test and a load test, as a fuel injector coil can pass a resistance test but still fail under a load.
Paint and Rust Removal:
Any loose paint and rust on the metal injector bodies are carefully removed using a wire brush. This step is skipped for plastic injectors.
Disassembly and Recleaning:
The filter baskets, O-rings, and pintle caps are removed. The injectors are then re-cleaned to ensure that any particles or dirt that may contaminate the cleaning fluid in the next step are removed.
Ultrasonic Cleaning:
The injectors are placed in an ultrasonic cleaning tank and electronically cycled on and off while being ultrasonically cleaned with special detergents. This process uses ultrasonic waves to agitate and dislodge any particles, carbon buildup, gum, and varnish, both outside and inside the injectors.
The cleaned injectors are now ready for flow testing. This typically includes a static flow test and a dynamic (pulsed) flow test:
- Static Flow Test: The injectors are flow tested for 15 seconds at a specific fuel pressure (43.5 psi or 3 BAR) while held fully open.
- Dynamic Flow Test: The injectors are tested for 30 seconds at different duty cycles, with varied pulse widths to simulate real-world conditions such as idling, acceleration, and high speed.
Leak Inspection:
All injectors are meticulously inspected for leaks on the injector body and at the output nozzle.
Ohm Testing:
A simple Ohm test is performed to verify the condition of the injector coil by testing the resistance across the terminals of the injector connector.
Final Steps:
After flow testing, new filter baskets, O-rings, and pintle caps are installed if needed. The injectors are then lubricated and sealed in Poly bags. A comprehensive test report is prepared and returned with the injectors.
It is important to note that some companies offer additional services, such as expedited cleaning and flow testing, seal replacement, and mailing instructions for sending in your injectors for cleaning and flow testing.

Soaking in injector cleaner
Soaking your fuel injectors in a cleaning solution is one way to clean them without removing them from your 2007 Ford Mustang. This method is often referred to as a "seafoam treatment". It involves adding a cleaning solution to your fuel tank, which is then run through the injectors, supposedly breaking up and cleaning out carbon deposits.
There are a variety of different cleaning solutions available on the market, including Techron, Chevron Techron, and Amsoil PI. Techron is a popular choice, but some consider it to be mild, and users have reported that it does not cause an adverse reaction when used in their vehicles. Chevron Techron is also safe to use with ethanol. Amsoil PI is considered to be the strongest fuel injector cleaner available. B12 Chemtool is another option, but it must be kept in a metal container as it will eat through plastic bottles.
To perform the seafoam treatment, simply add the cleaning solution to your fuel tank and then run your engine. Some recommend running the engine with the cleaner for a more concentrated clean, while others suggest using a detergent additive in the tank instead of a stronger cleaner. It is important to note that some cleaning solutions will wipe out your spark plugs, so you will need to replace them afterward.
While this method of cleaning fuel injectors is convenient, some people believe that it is not as effective as removing the injectors and having them professionally cleaned and/or flow-tested. Additionally, if the injectors are very dirty, they may need to be removed and soaked in the cleaning solution directly, rather than running the solution through them while they are still in the car.

Manual flushing
If you are looking to manually flush your fuel injectors, you will first need to remove them from your 2007 Ford Mustang. You can then take them to a local fuel injection specialty shop, where they will have the necessary equipment to clean and flow test the injectors. This service is typically inexpensive, with some shops charging as little as $5 per injector for cleaning and flow testing.
If you would prefer to clean the injectors yourself, you can use a fuel injector cleaner. There are a variety of products available, including Chevron Techron, 3M, Seafoam, Wynn's, STP, and Gumout. These products can be added directly to your fuel tank or used with a kit that connects to the fuel rail. When using a kit, you will need to disable your fuel pump and run the cleaner until the canister is empty.
It is also possible to soak the tips of the injectors in a cleaning solution, although the effectiveness of this method is unclear. Some people also recommend using fuel injector cleaners and Seafoam through the gas tank while the injectors are still in the car, but others suggest that this is not as effective as a professional cleaning.
It is important to note that the filters inside the fuel injectors are very small, and if they become damaged or clogged, it may be more cost-effective to simply purchase new injectors.

Using fuel injector cleaning kits
While there is some debate about the effectiveness of fuel injector cleaning kits, they can be a good option for regular maintenance of your 2007 Ford Mustang. Here is a guide on how to use a fuel injector cleaning kit:
First, purchase a reputable fuel injector cleaning kit. There are many options available on the market, such as those offered by Chevron, 3M, and Firestone. Consider your budget and the reputation of the brand when making your decision. Some popular options include:
- Chevron Techron Fuel Injector Cleaner (black bottle)
- 3M Fuel Injector Cleaner
- Firestone Fuel Injector Cleaner
Once you have your chosen kit, follow the instructions provided by the manufacturer. Each kit may have slightly different instructions, so it's important to read and understand the specific steps outlined by the brand. Here are some general steps that may be involved:
- Prepare the vehicle: Park your Mustang on a level surface and ensure the engine is cool. Open the hood and locate the fuel rail.
- Disable the fuel pump: This step is crucial as it ensures that the cleaning fluid will flow through the fuel injectors. Refer to your Mustang's manual to locate the fuel pump relay or harness and disable it.
- Connect the cleaning kit: Follow the kit's instructions to properly connect the cleaner to the fuel rail. This may involve attaching hoses and connectors.
- Run the cleaner: Start the engine and let it run until the bottle of cleaning fluid is empty. The fluid will flow through the fuel injectors, helping to break down and remove carbon deposits and other buildup.
- Re-enable the fuel pump: Once the cleaning fluid is empty, stop the engine and re-enable the fuel pump by reconnecting the relay or harness.
- Test the vehicle: Start the engine again and take your Mustang for a test drive. Notice if there are any improvements in performance, such as smoother acceleration or improved fuel efficiency.
It is important to note that while fuel injector cleaning kits can be effective for regular maintenance, they may not be sufficient for heavily clogged or damaged fuel injectors. In such cases, it is recommended to seek professional cleaning services or consider replacing the fuel injectors altogether. Additionally, always refer to your vehicle's manual and follow safety precautions when performing any maintenance or repairs.
