* Engine misfires
* Rough idling
* Stalling
* Reduced power
* Poor fuel economy
* Check engine light illumination
Specific symptoms of fuel injection problems can vary depending on the type of fuel injection system. For example, vehicles with electronic fuel injection (EFI) may experience different symptoms than vehicles with mechanical fuel injection (MFI).
EFI systems use a computer to control the fuel injectors, while MFI systems use a mechanical linkage. EFI systems are more precise than MFI systems, but they can also be more complex and susceptible to problems.
Some common fuel injection problems include:
* Clogged fuel injectors: Clogged fuel injectors can prevent fuel from reaching the engine, causing engine misfires, rough idling, and stalling.
* Leaking fuel injectors: Leaking fuel injectors can cause fuel to drip into the engine, causing engine flooding, rough idling, and stalling.
* Faulty fuel injector sensors: Faulty fuel injector sensors can provide incorrect information to the computer, causing the computer to inject too much or too little fuel. This can cause engine misfires, rough idling, and stalling.
* Computer problems: Computer problems can affect the fuel injection system, causing a variety of symptoms, such as engine misfires, rough idling, and stalling.
* Fuel injector seal leak: This can cause fuel injector cleaner or gasoline to leak out from around the fuel injector o-ring. This can lead to a loss of pressure and fuel efficiency, as well as engine misfires and stalling.
If you experience any of these symptoms, it is important to have your vehicle inspected by a qualified mechanic. Fuel injection problems can be serious and can lead to engine damage if they are not repaired.
