Clogged or Leaking Fuel Injectors Can Cause Engine Performance Issues

Fuel injectors have replaced the carburetor in modern automotive technology, and these tiny wonders help improve your engine performance when they are clean and operating as they should be. The injectors have tiny nozzles that spray fuel into the cylinders to start engine combustion. George Automotive Services advises that over time the fuel injectors will get clogged by carbon deposits. They can also start leaking. If they do, you may notice one or more of the following problems below.

Dancing Tachometer Needle

If the fuel injectors are clogged, the fuel will make its way into the cylinders in spurts. This can affect how well the spark plugs ignite the air and fuel and, as a consequence, your engine RPMs may go up and down. When this happens, you will see it on your tachometer needle, as it will dance up and down.

Misfiring Engine

The spotty fuel delivery can also cause your engine to misfire. The more the clogged fuel injectors affect the balance of air and fuel in the cylinders the more your engine will misfire. You will feel the misfires as well as hear them. In severe cases, you may also end up with a stalling problem.

Poor Fuel Economy

If the fuel injectors are leaking, the engine will burn away the excess fuel. You will notice that you are getting significantly less gas mileage than you normally do with this problem. If you keep track of your gas mileage, you may notice the difference right away. If you don’t, you may find yourself heading to the service station more often in the problem could be due to leaking fuel injectors.

Rough Idling

As with engine misfiring, clogged fuel injectors can also affect how well your vehicle idles. Instead of idling smoothly, the vehicle will idle roughly. You will feel your engine stuttering and you will hear the idle struggling. This can be a sign of a problem with the fuel injectors or another fuel delivery problem such as a malfunctioning fuel pump. If your fuel filter is clogged, this, too, will affect how much fuel makes its way into the engine.

Dead Engine

Finally, if a clog is preventing fuel from making its way into the engine at all, you will be unable to start your automobile. You will notice the signs listed above before your engine dies completely, so make sure to visit our shop at the first sign of trouble.
