It is never pleasant to perceive an injector noise on your Lexus GS. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be related to multiple types of complications with your automobile injectors. It may not be anything major, but when a repeated noise arises, you have to be sure. Specifically since replacing your Lexus GS’s injectors can be costly. That’s why our team decided to prepare this article content in order to help you see more clearly, learn about the different plausible failures and determine your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Lexus GS, then at the plausible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very important element of the operation of your engine motor. They were introduced to the modern cars 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 opportunity, 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 compiled from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their aim 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 coming from the injectors of your Lexus GS
Discovering injector noises on your Lexus GS may result from different origins, we will now concentrate on the potential causes of these. In most cases, 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 stop them. If you perceive another clicking noise but it is not from your injectors, we recommend you to examine this article content about clicking noise on Lexus GS to discover the reason.
The reasons for injector clicking or knocking noise Lexus GS
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Lexus GS have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its task is to control 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 modified, the main role of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Lexus GS. The main reason of these situations generally comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably end in a malfunction of the injector.

The repercussions of injector noise on Lexus GS
Now that we have reviewed the several reasons for injector noise on your Lexus GS, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these repercussions which can fairly quickly become critical….
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 repercussions felt by drivers is a severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks connected with 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>
