It is hardly ever enjoyable to experience an injector noise on your Chevrolet Malibu. It is a noise that appears regularly, usually when you accelerate or your engine is idling. However, this indication may be relating to several types of trouble with your car injectors. It may not be anything major, but when a continuing noise shows up, you have to be sure. Especially since repairing your Chevrolet Malibu’s injectors can be expensive. That’s why our team decided to write this article content in order to help you see more clearly, learn about the different possible failures and distinguish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Chevrolet Malibu, then at the possible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very important element of the operation of your engine motor. They were introduced to the modern automobiles about 20 years ago. Before their appearance, more conventional carburettor-type intake systems were employed, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the possibility, thanks to the injectors pump, to control electronically each stage of the intake process very precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data obtained from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their objective is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to obtain the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise caused by the injectors of your Chevrolet Malibu
Discovering injector noises on your Chevrolet Malibu may result from different locations, we will now center on the potential triggers of these. Generally, the common noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be applied to prevent them. If you experience another clicking noise but it is not from your injectors, we advise you to browse this article content about clicking noise on Chevrolet Malibu to find the trigger.
The causes for injector clicking or knocking noise Chevrolet Malibu
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Chevrolet Malibu have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes is altered, the main role of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Chevrolet Malibu. The main trigger of these problems usually originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector.

The end result of injector noise on Chevrolet Malibu
Now that we have examined the different causes for injector noise on your Chevrolet Malibu, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can fairly quickly become severe….
First, you risk destroying your exhaust system in the long run, because the unburned fuel residues that will end up in your exhaust system can corrode the metal in it.
One of the most common consequences experienced by drivers is a distinctive loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks connected to your injectors and protect you from engine failure:
- Do not drive at the bottom of the tank, as you may absorb impurities
- Use quality fuel
- Think of changing your diesel fuel filter regularly>
