Mechanics is a relatively logical area. But if there is indeed a problem that is sometimes difficult to explain, it is an unstable idle or acceleration holes. Whether for a Smart For-us, or any model of automobile. But we can help you understand. Undeniably, the origin can come from a good quantity of components of the engine block, or even electronic. To find the origin of the breakdown of your Smart For-us, you will have to follow a fairly simple procedure. But above all, let's see the signs of a faulty idle.
Idle problem on a Smart For-us: the symptoms
Un unstable idle close to stall . This is really the most common slow motion problem. This impression that the engine may stall while driving at an ordinary speed, or that the Smart For-us grazes . It even happens that stalling occurs. It is therefore a real danger for the driver. In this case, don't wait too long to take care of it. We invite you to do your own checking through the paragraph below. We can also understand that the Smart For-us has a acceleration problem . No more reports this time with an idle problem. Losses of power and acceleration holes may occur for various reasons. These two symptoms should not be confused. We invite you to read our files concerning power losses.
Smart For-us: develop a diagnosis to understand the origin of idling
You need to start by performing a number of extremely simple checks, before going into a little more detail.
Idle speed of Smart For-us: exhaust fumes.
A black smoke escapes from the exhaust. This generally means that the air and fuel mixture is bad. Or that your air filter is clogged. In both situations, an idle problem can occur on this Smart For-us. A White smoke escapes from the exhaust. This time again it can come from a disturbance. White smoke is usually water vapor. It is thus possible that it is an intake or cylinder head gasket problem.
Checking the engine block components
As we have demonstrated, an idle problem on this Smart For-us can come from many constituents. You will therefore have to take the time to carefully scan the engine block. However, it is recommended to be very careful and not to touch the engine block components too much, as this could amplify the malfunction or divert the nature of the problem. We obviously recommend that you go to an auto repairer for a more in-depth audit. Here are therefore point by point the elements to be examined.
- The first thing to do is check all hoses . These can be drilled, or even detached.
- You should also check the sensors and sensors of your engine block. It is however complex to check their correct functioning. You can find tutorials on youtube, and it usually requires electronic devices.
- Perform a check of pressures Hydraulic. Again, the pressure controls require suitable tools.
Idling problems are common, however, are hard to diagnose. A visual check on the Smart For-us gives the opportunity to have an idea, however it is more judicious not to tackle amateur DIY.
