Mechanics is a rather Cartesian field. However, if there is a problem that is sometimes complex to explain, it is an unstable idle or acceleration holes. Whether it concerns a seat leon, or for any other car model. However, we can help you understand. And yes, the cause can come from a good amount of engine parts, even electronic. To find the origin of the failure of this seat leon, it will be necessary to follow a strict method. But first of all, we will see the symptoms of a faulty idle.
Idle problem on a seat leon: symptoms
Un unstable idle close to stall . This is undoubtedly the most common problem in slow motion. This feeling that the vehicle will stall while driving at a normal speed, or that the seat leon grazes .

Losses of power and acceleration holes are going to happen for many reasons. These two different concerns should not be confused. We invite you to read our posts related to power losses.
seat leon: develop a diagnosis to understand the origin of idling
You have to start by performing a number of extremely simple checks, before going into more detail.
Seat leon idle: exhaust fumes.
A black smoke emanates from the exhaust. This generally means that the air and fuel mixture is out of order. But also that the air filter is obstructed. In both cases, an idling problem can occur on this seat leon. A White smoke emanates from the exhaust. This time again it can come from a fault. White smoke is usually water vapor. It is therefore likely that it is an intake or cylinder head gasket problem.
Engine components check
As we have shown, an idle problem on a seat leon can come from many components. You should therefore try to inspect the engine carefully. However, it is recommended to be extremely careful and not to touch the engine components too much, as this can aggravate the malfunction or conceal the source of the problem. We of course recommend that you go to an auto repairer for a more suitable diagnosis. Here, therefore, point by point, the constituents to be checked.

- You also need to check the sensors and sensors of your engine. It is however complicated to check their correct operation. You can find tutorials on youtube, and it usually requires electronic devices.
- Perform a check of pressures hydraulic. Again, pressure controls require appropriate equipment.
Idle malfunctions are common but are difficult to diagnose. A visual check on the seat leon will allow you to have a clearer vision, but it is wiser not to tackle amateur DIY.
