Fuel injector resistance test
Fuel injectors are components that use an electrical signal to deliver a precise amount of fuel into your engine. As they get older or dirty, they can start to malfunction. While a mechanic can perform a test to determine if your fuel injectors are working properly, this can be costly.
To test the fuel injectors on your 2006 Ford Expedition, you can start by locating the fuel injectors in your vehicle. There is one per cylinder, typically a black plastic housing installed directly above the cylinder. With the vehicle off, disconnect the electrical connector for the fuel injector and use a multimeter or an ohm meter to take a resistance reading. Check your vehicle's service manual or look online to learn the correct value (most fuel injectors should read between 10 and 18 ohms). The resistance of the coils should be within about plus or minus 10% of each other. Reconnect the injector and check the next one. All readings should be within the range suggested by the manufacturer and should be the same for all of your injectors. If any resistance readings are off, the faulty injector needs to be repaired or replaced.
If you suspect your fuel injectors are causing problems because of dirt, gunk or carbon buildup, they won't get better on their own. On the contrary, the problem will only get worse until your vehicle stops running. You can use a fuel system product to clean dirty injectors and get your vehicle's performance, fuel economy and drivability back to normal.

Fuel injector maintenance
Fuel injectors are integral to the performance of your car, delivering fuel to the combustion chamber and ensuring the engine burns fuel efficiently. Therefore, it is important to maintain them and keep them clean and unclogged.
There are a few signs to look out for that indicate your fuel injectors are clogged or dirty. A clogged fuel injector will cause your engine to idle roughly or stall, and you may experience a lack of power or hesitation when accelerating. You may also burn more fuel and get worse fuel economy. Before it gets to this point, your vehicle's 'Check Engine' light will probably turn on, giving you a chance to take action.
There are a few ways to clean your fuel injectors. Firstly, you can use a fuel injection cleaning kit or fuel system additives. These can be purchased for a relatively low cost and can be poured directly into the gas tank. However, some people feel that these become too diluted to be effective. Alternatively, you can use a pressurised canister with the cleaner and fuel and run it through the fuel rail with the engine running. This method is more expensive but is a good maintenance service for high-mileage cars.
If you want to clean your injectors without the use of chemicals, you can remove them from the engine and clean off any gunk that has built up. This is the best way to thoroughly clean your injectors.
There are also steps you can take to prevent your fuel injectors from clogging. Fuel contains detergent additives to prevent clogging, but these are not always effective. Using a fuel injector with a stainless steel calibration slide and spring assembly will prevent corrosion within the fuel control body, extending the service life of your injector.
