From the moment you descend below a certain speed your car starts to slow down and quite often even the engine stops for no obvious reason?
It seems obvious that this is abnormal. In this article we will try to give an answer so that you can see more clearly before potentially going to the garage and get a steep bill to repair your Mitsubishi Mirage.
Obviously, if this happens when driving at quite high speeds, do not take any more unnecessary risks. Call a professional urgently. Imagine that this happens to you on the ring road or highway….
First thing to take into account, and it may seem unfamiliar, but it has occurred to some people before: Do you get fuel all the time at the same pump for your Mitsubishi Mirage? In this case, it could come from there. Try changing gas pumps, and see what happens. This is improbable but it doesn’t cost much to try it. The fuel you get from here may contain dirt or impurities that damage your Mitsubishi Mirage’s engine.
If nothing changes, let’s take a look at the more technical causes you are confronted with on your Mitsubishi Mirage.
Electronic part of your Mitsubishi Mirage :
The first element is the MCU (Motor Control Unit) box. You may wonder what this piece is. In a few words , it is a metal box consisting of a multitude of electronic elements whose purpose is to receive electrical signals, developing these data, and sending information to the various parts of your Mitsubishi Mirage. It is a base to manage your car’s information.
As you have understood, if it were to malfunction, the consequences could be serious for your Mitsubishi Mirage. A motor that stops can be a indication.
Apart from that, check out the engine speed sensor side, or the onboard computer. It is a platform for swapping calculations and is therefore vital to the engine.
Another potentially targeted box is the built-in systems interface, which centralizes all the information from the multiple sensors throughout your vehicle. It operates as a relay platform for all your calculators. It is equivalent in some ways to a computer motherboard. So you figure out the importance of this on your Mitsubishi Mirage.
As to sensors, also consider your TDC sensor.Its role is to send information to the calculators concerning the position of the pistons in order to determine the engine speed, which will then determine the fuel injection.
Last but not least, consider your alternator, which would no longer allow your Mitsubishi Mirage to be powered. Same concern if it came from the ignition coil.
Finally, because this case is much rarer, it might happen that a wire or connection is damaged, and your computer could no longer function properly.
So here’s for the electronic causes. Let’s now look at the mechanics on your Mitsubishi Mirage.
Mechanical part of your Mitsubishi Mirage :
First, only a blocked filter can affect the life of your engine. Bear in mind to clean it regularly. The injection pump, or even the pressure regulator, are also parts to be examined.
The idle actuator could also very well be involved .
Its purpose is to regulate the engine speed within the complete idle control of the engine management system. ThereforeInstantly affecting the engine .
Another factor, more rare but also possible, is Neiman’s contactor. It is what enables to lock the steering wheel for safety when the ignition is turned off. It is related to the engine so a failure may well also have implications on the Mitsubishi Mirage’s engine.
Here are the main motives, whether electronic or mechanical, that might lead to your Mitsubishi Mirage to slow down.
In a few words, first check the simplest things, dirty pieces, then find out about the electronic parts that may be involved.
If you were about to start fixing on your own, be really thorough on what you do, there is no alternative for the expertise of a professional.
