Mechanics is a fairly methodical field. But if there is a problem that is sometimes hard to explain, it is an unstable idle or acceleration holes. Whether it concerns a Lancia Delta, or for any other type of vehicle. But we are here to help you. Undeniably, the cause can come from many components of the engine, even electronic. To find out the nature of the Lancia Delta's breakdown, you will have to follow a strict procedure. But first, let's see the signs of a faulty idle.
Idling problem on a Lancia Delta: symptoms
Un unstable idle close to stall . This is completely the most common idle malfunction. This feeling that the vehicle can stall while driving at a normal speed, or that the Lancia Delta grazes . Sometimes it happens that stalling occurs. In this situation, it is really dangerous for the driver. In this case, do not delay in worrying about it. We invite you to carry out a diagnosis through the paragraph below. We can also understand that your Lancia Delta has a acceleration malfunction . No link this time with a low speed dysfunction. Losses of power and acceleration holes can occur for multiple causes. These two different concerns should not be confused. We advise you to browse our articles related to power losses.
Lancia Delta: developing a diagnostic to understand the origin of the idle
We have to start by performing several very easy checks, just before going into a little more detail.
Lancia Delta idle: exhaust fumes.
A black smoke comes out of the exhaust. This usually means that the air and fuel mixture is out of order. Or that the air filter is clogged. In both situations, an idle malfunction may occur on the Lancia Delta. A White smoke comes out of the exhaust. In this case also it can come from a disturbance. White smoke is usually water vapor. It is therefore possible that it is a malfunction of the intake or of the cylinder head gasket.
Engine components check
As we said, an idle malfunction on a Lancia Delta can be caused by many constituents. You should therefore try to inspect the engine carefully. However, it is still suggested to be very careful and not to tamper with the components of the engine, as this could amplify the malfunction or divert the cause of the malfunction. We naturally recommend that you go to a garage for a more in-depth audit. These are therefore point by point the components to be checked.
- The first thing to do is check all of the hoses . These can be pierced or even detached.
- You should also check the sensors and sensors of your engine. It is however complex to check their correct functioning. You can find tutorials on youtube, and it often requires electronic devices.
- Perform a check of pressures Hydraulic. Again, the pressure controls require adequate tools.
Idling problems are common but are difficult to diagnose. A visual check on your Lancia Delta will allow you to have a clearer vision, but it is wiser not to venture into amateur DIY.
