Mechanics is a rather logical area. However, if there is indeed a phenomenon that is sometimes difficult to explain, it is an unstable idle or acceleration holes. Whether it concerns a Lancia Delta 2, or any other car model. However, we can help you understand. Indeed, the cause can come from many components of the engine block, even electronic. To find the nature of the breakdown of this Lancia Delta 2, you must follow a fairly simple methodology. But before, we will see the symptoms of a slowed down idle.slow-motion-problem-Lancia-Delta-2

Idling problem on a Lancia Delta 2: symptoms

Un unstable idle close to stall . This is undoubtedly the most recurrent dysfunction in slow motion. This feeling that the engine will stall while traveling at a normal speed, or that the Lancia Delta 2 grazes . It may also happen that the vehicle stalls. It is therefore really dangerous for the driver. In this case, do not delay taking care of it. We invite you to do a check via the paragraph below. We can also understand that the Lancia Delta 2 has a acceleration malfunction . No connection this time with an idle malfunction. Losses of power and acceleration holes can occur for various causes. These two phenomena should not be confused. We advise you to read our articles on power losses.

Lancia Delta 2: develop a diagnostic to understand the origin of the idle

We must start by carrying out several very easy checks, before going into even more detail.

Lancia Delta 2 idle: exhaust fumes.

A black smoke escapes from the exhaust. This generally means that the air and fuel mixture is bad. Or the air filter is clogged. In both cases, an idle malfunction can occur in this Lancia Delta 2. A White smoke escapes from the exhaust. This time too, it can be the result of a fault. White smoke is usually water vapor. It is therefore plausible that it is a malfunction of the intake or the cylinder head gasket.

Checking the engine block components

As we have shown, an idle malfunction on a Lancia Delta 2 can come from several components. So try to run through the engine block carefully. However, it is suggested to be very careful and not to tamper with the engine block connections, as this could worsen the breakdown or conceal the nature of the malfunction. We naturally recommend that you go to a mechanic for a more detailed diagnosis. So here are step by step components to examine.

  • The first thing to do is check all hoses . These can be perforated, or even detached.
  • You should also consider the sensors and sensors of your engine block. It is however complex to control their good functioning. You can find tutorials on youtube, and it usually requires electronic devices.
  • Perform a check of pressures Hydraulic. Again, pressure checks require appropriate tools.

Idle worries are common however are complex to diagnose. A visual check on the Lancia Delta 2 allows you to have an idea, however it is wiser not to venture into amateur DIY.
