It is rarely ever pleasant to notice an injector noise on your Toyota 86. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this warning sign may be related to different sort of trouble with your car injectors. It may not be anything serious, but when a persistent noise shows up, you have to be sure. Especially since fixing your Toyota 86’s injectors can be costly. That’s why our team decided to create this content in order to help you see more clearly, learn about the different possible failures and identify your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Toyota 86, then at the possible causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very important component of the operation of your engine motor. They were launched to the modern vehicles about 20 years ago. Before their arrival, more conventional carburettor-type intake systems were used, 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data accumulated from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their purpose 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 based on the injectors of your Toyota 86
Discovering injector noises on your Toyota 86 may result from different sources, we will now look into the potential triggers of these. Generally, the regular noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be applied to prevent them. If you notice another clicking noise but it is not from your injectors, we recommend you to browse this content about clicking noise on Toyota 86 to locate the trigger.
The reasons for injector clicking or knocking noise Toyota 86
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Toyota 86 have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three attributes is altered, the main purpose 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 induce thoses knocking or clicking noises on your Toyota 86. The main trigger of these situations generally comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector.

The side effects of injector noise on Toyota 86
Now that we have reviewed the different causes for injector noise on your Toyota 86, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can quickly become serious….
First, you risk destroying your exhaust unit 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 basic repercussions noticed by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly damage your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks associated 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>
