The Signs of Clogged Fuel Injectors in Your Automobile

No Comments

If the fuel injectors get clogged or leak, your engine will start to have performance issues. AutoFix lists those issues below. If your vehicle is suffering from any of the following, bring it to our shop. We can find out whether your fuel injectors are the problem, or whether you have another issue such as a malfunctioning fuel pump or vacuum leak.

Bad Fuel Economy

Leaking fuel injectors will significantly reduce your vehicle’s gas mileage. This is because the excess fuel that is leaking out of the injectors is being burned in the combustion chamber. You will end up heading to the service station more often to fill your tank. Replacing the leaking fuel injectors will restore your vehicle’s fuel economy.

Dead Engine

If the fuel injectors are completely clogged, you may end up with a dead engine. Simply put, there is no fuel in the combustion chamber in order to fire up the engine and keep it running. Severely clogged fuel injectors can be professionally cleaned to restore their functionality. Provided they aren’t leaking, as well, cleaning usually does the trick.

Misfiring Engine

Clogged fuel injectors will also cause your engine to misfire. This is because there is more air than fuel in the combustion chamber and the engine will struggle to run. The engine can also misfire if the fuel injectors are leaking because the combustion chamber is getting spurts of fuel that it doesn’t need. A misfiring engine will sputter or surge.

Rough Idling

The misfiring can also affect how well your engine idles. You may notice that your idle has gotten rough because the fuel injectors are clogged or leaking. Again, as with the misfiring engine, the reason why your vehicle’s engine is idling roughly is that it either has too much air or too much fuel in the combustion chamber. Cleaning the fuel injectors or replacing them can help.

Sporadic RPMs

Finally, clogged fuel injectors can affect your engine’s RPMs. You will see this problem reflected if you keep an eye on the tachometer on your dashboard. You may notice that the RPM needle is dancing up and down because the revolutions per minute are sporadic. This is due to an uneven influx of fuel heading into the combustion chamber to be burned.
