Diagnosing A Clogged Or Leaking Fuel Injector

Clogged Or Leaking Fuel Injector

We usually leave the more intricate car tech-talk to the mechanics. After all, you don’t need to know each and every part of your car to drive one. We often don’t bother with engine parts or fuel injectors because they can be too complicated to understand and dangerous to meddle with.

However, even if you aren’t going to touch, customize or alter them, it is still worth noting the various signs that could indicate that there is a problem with your vehicle, particularly the engine. Sometimes mechanics catch these problems too late because car owners don’t regularly have their car checked or maintained.

Unfortunately, that develops into bigger and more costly problems. So let’s avoid that because we all know every one of us doesn’t want to lose more money with our vehicles when we can prevent it in the first place.

This post will discuss the different signs of having a clogged or leaking fuel injector. If you see any of such signs, it is best to bring them to a mechanic and don’t wait for your engine to completely fail and get you stuck on the road.

Poor Fuel Economy

Some cars may be more fuel-efficient than others. However, in this case of poor fuel economy, you have to compare your car’s fuel economy to the previous months of use. Due to the fuel leaking, you’ll be wasting fuel and will significantly reduce gas mileage.

Instead of the fuel being burned efficiently by the engine, it’ll be out of the combustion chamber. Leaking fuel injectors cause you additional gas money. The simple remedy is to replace the leaking fuel injectors with a reputable mechanic.

Engine Is Dead

When your engine is dead, it can be troubling. The engine is one of the most expensive parts of your vehicle. However, before you think of trashing your car and sending it off to the wrecker, you might want to have the fuel injectors checked first.

A dead engine can be caused by a fuel injector that’s completely clogged. When this happens, fuel can’t get into the combustion chamber to start the engine and make it work. Your engine may be working perfectly. It just doesn’t have the requirements it needs to work.

A simple solution to this is to have the clogged fuel injector cleaned by a professional. If they are not leaking, cleaning will do the trick.

Engine Misfire

In order for the engine to work efficiently, it needs the proper proportion of fuel to air. In the case of clogged fuel injectors, there will be more air in the combustion chamber as compared to the fuel. That could lead to a struggling engine that misfires.

Alternatively, the fuel injector may also be leaking. Similarly, a leaking fuel injector doesn’t deliver the right amount of fuel to the combustion chamber. This leads to sputtering of the engine.

Sporadic RPMs

Keep an eye on your tachometer. If you notice that your RPMs are sporadic, which shows the needle bouncing up and down, there can be something wrong with your fuel injector. When the fuel injector is clogged or leaking, the fuel available will vary. That also means that the power available varies, which leads you to have sporadic RPM.

Rough Idling

Another sign of a clogged or leaking fuel injector is the rough idling of your engine. Just like the other signs, this has something to do with not being able to provide enough fuel for the engine to burn. It may have too much air or too much fuel. In such a case, cleaning or replacing the injector fuels will solve the problem.
