It is never pleasant to experience an injector noise on your Cadillac CTS. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this symptom may be relating to multiple sort of concerns with your car injectors. It may not be anything severe, but when a frequent noise happens, you have to be sure. Especially since replacing your Cadillac CTS’s injectors can be expensive. That’s why our team decided to write this article in order to help you see more clearly, learn about the different possible failures and establish your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Cadillac CTS, then at the possible triggers from which an injector noise may come.
Attributes of the injectors
Injectors are a very fundamental element of the operation of your engine. They were brought in to the modern vehicles 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 accurately (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 goal 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 triggers of a clicking or knocking noise coming from the injectors of your Cadillac CTS
Hearing injector noises on your Cadillac CTS may originate from different locations, we will now focus on the potential causes of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be adopted to stop them. If you experience another clicking noise but it is not from your injectors, we encourage you to read this article about clicking noise on Cadillac CTS to discover the cause.
The reasons for injector clicking or knocking noise Cadillac CTS
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Cadillac CTS have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three features 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 Cadillac CTS. The main cause of these concerns generally originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably result in a malfunction of the injector.

The side effects of injector noise on Cadillac CTS
Now that we have examined the different causes for injector noise on your Cadillac CTS, 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 repercussions which can quickly become major….
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 known effects experienced by drivers is a significant loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly affect your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks relating 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>
