Fuel injectors are an essential component of a car's engine, and keeping them clean is crucial for optimal performance. While there are various methods for cleaning fuel injectors in a Mustang, the most effective approach involves using a professional service or a factory kit. This process requires disabling the fuel pump and running a detergent through the fuel rail until the canister is empty. For extremely dirty injectors, a high-concentrate cleaner may be necessary, but these can be dangerous and should be handled by professionals. Regular maintenance with a fuel injector cleaner, such as Chevron Techron, added to the tank is also recommended. Sea Foam is another popular option for cleaning injectors, but it may not be as effective for removing dirt and carbon deposits. The cost of professional cleaning services can vary, with some shops charging as little as $5 per injector, while others quote prices closer to $100. Overall, keeping fuel injectors clean is essential for maintaining the performance and longevity of a Mustang's engine.

What You'll Learn
Using a professional service
If you're not confident in cleaning your Mustang's fuel injectors yourself, it may be a good idea to use a professional service. While it can be more expensive than doing it yourself, a professional service will ensure the job is done properly and safely, and could save you money in the long run by preventing engine damage.
Injector Rx is one company that offers a fuel injector cleaning service. They use a computer-controlled testing machine to test the injectors for any issues, and then employ an ultrasonic cleaning method to restore dirty, clogged, or leaking fuel injectors to a like-new condition. They also offer a while-you-wait service for local customers, and will ship the injectors back to you within 24 hours of service completion.
Another option is to take your car to a garage, such as Jiffy Lube, for a fuel system cleaning service. This will help remove deposits and residue from your fuel system, injectors, and combustion chamber, which can build up over time and cause reduced performance.
When choosing a professional service, it's important to consider the cost, the turnaround time, and the company's reputation and experience. It may be worth getting quotes from multiple companies and reading reviews before making a decision.
Additionally, some companies, such as RC Engineering, offer complete rebuilds and flow tests for fuel injectors. This may be a good option if your injectors are original and you want to ensure they are in the best possible condition.

Home cleaning kits
There are several home cleaning kits available for cleaning Mustang fuel injectors. One method is to use a fuel injector cleaner, such as Amsoil PI, which is considered the strongest on the market. Other options include BG44, Chevron Techron, and Lucas additives. These cleaners can be added to the fuel tank or fuel rail, and it is recommended to refer to the manufacturer's instructions for proper usage. Additionally, some automotive machine shops offer injector cleaning services for around $5 per injector, which can be a convenient and cost-effective option.
Another approach is to use a stand-alone machine to clean the injectors. This method often involves chemicals or sound waves to clean the injectors and then flow testing them to ensure proper functioning. However, this option can be cost-prohibitive compared to simply purchasing new injectors.
It is worth noting that some people have expressed concerns about the effectiveness of certain cleaners, such as Seafoam, which can be pricey and may not deliver the desired results. Additionally, it is generally recommended to have injectors professionally cleaned by an auto repair facility, as they will use higher-quality cleaners and produce better outcomes.
For those who prefer a DIY approach, it is possible to take the injectors apart and clean them manually. However, this can be a complex task, and it is important to ensure that the injectors are properly reassembled. It is suggested to refer to online videos or guides for detailed instructions on disassembling and reassembling fuel injectors.

Fuel additives
One popular option is Seafoam, which is cheap and available at car shops. It is recommended to use it once or twice a year to keep the valves and pistons free of carbon buildup. However, some people warn against using Seafoam, as it is intended for weed whackers and can cause the engine to run hotter.
Another option is Amsoil Performance Improver and Amsoil Upper Cylinder Lubricant, which are also recommended by some users. These products are said to help restore lost horsepower through dirty injectors.
Other fuel additives that have been mentioned include STP, Berryman B-12, Redline SL-1, and Techron Concentrated. Techron is said to be recommended by Ford and is available at Chevron stations and some parts stores. It is also available in a supreme version, which is more expensive but can be used regularly.
Some users have also mentioned using Xylene, which can be found in hardware stores, but this should be avoided as it can dissolve rubber components in the carburettor.
It is important to follow the instructions and use the specified amounts when using any fuel additive to avoid potential damage to your engine.

Flow testing
There are a few ways to go about flow testing. One option is to send your injectors to a professional service or automotive machine shop that has an injector cleaner/test stand. These shops will not only clean your injectors but also identify any that are not performing optimally. Some shops may also offer a complete rebuild service for original injectors. This option can be cost-prohibitive, with some shops charging close to $100 to clean eight injectors, but it ensures the job is done correctly and can save you money in the long run by extending the life of your engine.
Another option is to purchase an injector flow testing kit and do the job yourself at home. This method can be more cost-effective, but it requires more time and effort. When doing it yourself, it is important to disable your fuel pump and ensure that the kit taps into the fuel rail. You then run the test until the canister is empty.
It is worth noting that some people choose to replace their fuel injectors rather than clean them, as the cost of cleaning per injector can sometimes be more than the cost of a new injector. However, this decision should be made carefully, considering the age and condition of the injectors, as well as the potential benefits of a thorough cleaning and flow testing service.

Cost of cleaning vs replacement
Fuel injector cleaning service is a controversial vehicle maintenance procedure that is often recommended by repair chains, independent shops, and dealers. However, it is rarely listed in vehicle owner's manuals. The price of this service typically ranges from $150 to $200, and when combined with a throttle body clean, the total cost can reach $250 to $300.
On the other hand, some shops may offer fuel injector cleaning by simply adding a bottle of solvent, which they may mark up significantly. This method is not only unnecessary but may also harm your engine. Additionally, some car manufacturers, like Mazda, specifically advise against using fuel system cleaning additives in their maintenance manuals.
For a Ford Mustang, the cost of replacing a bad injector can vary. A replacement set from Ford can cost over $300, while the same injectors from Ford Racing are priced at around $100. Considering the minimal difference in cost, some may opt to replace the injectors rather than spend $15 to $17 per injector for cleaning.
To save costs, some Mustang owners opt to clean their fuel injectors at home. This can be done by using fuel injector cleaners, such as Chevron Techron, Seafoam, or Wynn's, which can be purchased for a few dollars per bottle. However, it is important to note that these cleaners may not remove all types of dirt and grime from the injectors. Additionally, certain solvents, like Xylene, can be harmful to rubber components in the fuel system.
