Top 5 Symptoms of A Clogged Fuel Injector
The following are potential symptoms of clogged fuel injectors that are failing:
- Your engine is difficult to start
- The engine may have a rough idle
- As you press the gas pedal, your engine hesitates
- Poor overall performance, e.g., power levels, poor acceleration
- Gas mileage begins to decline
Check Engine Light
Note that other elements of your engine can also cause these issues. If the engine light is on in your dash, check for error codes to determine the cause. Verify that your air filter, fuel filter, spark plugs, and wires/coils are all in good condition. Also, check that the fuel pump is working correctly.
Vacuum Leaks
Confirm there are no leaks in vacuum hoses. Fuel injector maintenance requires several hours to complete, while these simple checks can be accomplished in minutes.
Poor Fuel Efficiency
Properly working fuel injectors spray precisely the amount of fuel mixture needed into your engine’s cylinder to deliver the amount of power required, for idling, acceleration, and cruising.
Faulty injectors that have deposits that are clogging them may stay open longer, allowing more fuel to enter the cylinder than required. This condition can also damage your cars catalytic converter, which is an expensive item to replace.
Dirty Fuel Injector
A bad fuel injector cannot deliver the amount of fuel trim needed. It may provide too little or too much for the operating conditions your engine is experiencing. A fuel injector that is not working usually does not deliver any fuel at all. There can be a total loss of fuel from that particular combustion chamber.
Rough Idling
Rough idling occurs when a car shakes or stumbles, or its RPM fluctuates while it is stationary, because the cylinders are not receiving a steady supply of fuel.
Why Do Fuel Injectors Become Dirty Clogged?
Hydrocarbons, sediment, and other materials in the fuel can clog a fuel injector over thousands of miles. Water in the fuel or gas tank can also cause rust which may pass through the fuel filter and clog the injectors. A clogged injector means failure in the fuel delivery to the engine. The result is one of the common reasons why your car wont start.
Can a Bad Fuel Injector Damage the Engine?
A bad or failing fuel injector can damage your engine. Remember that the fuel injectors are connected to the fuel lines and they deliver fuel pressure from the gas tank, if the fuel pressure drops this can cause engine misfire.
It usually starts with a check engine light signal that is a common misfire code. You can also notice a bad performing fuel economy when the fuel injectors are clogged.
