Mechanics is a fairly Cartesian profession. But if there is a phenomenon that is sometimes complex to explain, it is unstable idling or acceleration holes. Whether it concerns a hyundai i20, or any other type of car. But we can help you understand. Undeniably, the reason can come from a lot of parts of the engine block, even electronic. To detect the nature of the hyundai i20 failure, you must follow a strict method. But first, let's see the symptoms of a faulty idle.
Idling problem on a Hyundai i20: symptoms
Un unstable idle close to stall . This is completely the most common idle problem. This feeling that the vehicle will stall while driving at a normal pace, or that the hyundai i20 grazes . It can happen that the stall occurs. Therefore, it is really dangerous for the driver. If so, don't wait too long to worry about it. We invite you to make a diagnosis via the next paragraph. We can also understand that the hyundai i20 presents a acceleration problem . No more reports this time with a low speed problem. Losses of power and acceleration holes can occur for many causes. These two phenomena should not be confused. We invite you to read our files concerning power losses.
hyundai i20: develop a diagnosis to understand the origin of idling
We have to start by performing various very simple checks, just before going into a little more detail.
Idling of the Hyundai i20: exhaust fumes.
A black smoke escapes from the exhaust. This usually implies that the air and fuel mixture is bad. Or that the air filter is cluttered. In both cases, an idling problem can occur on the hyundai i20. A White smoke escapes from the exhaust. This time, too, it could be the result of a disorder. White smoke is usually water vapor. It is therefore plausible that it is a problem with the intake or the cylinder head gasket.
Checking the engine block components
As we have seen, an idling problem on the hyundai i20 can arise from many points. You should therefore take the time to inspect the engine block carefully. On the other hand, it is suggested to be extremely careful and not to touch too much with the components of the engine block, because this could worsen the failure or hide the nature of the problem. We of course recommend that you go to an auto repairer for a more in-depth audit. Here are therefore point by point the elements to check.
- The first thing to do is check all of the hoses . These can be perforated, or even detached.
- It is also necessary to control the sensors and sensors of your engine block. It is however difficult to control their proper functioning. You can find tutorials on youtube, and it usually requires electronic devices.
- Perform a control of pressures Hydraulic. Again, the pressure tests require appropriate tools.
Idling malfunctions are common but are hard to diagnose. A visual check on the hyundai i20 will allow you to have a clearer vision, but it is better not to venture into amateur DIY.
