Mechanics is a relatively Cartesian profession. But if there is one problem that is sometimes difficult to explain, it is unstable idling or acceleration holes. Whether it concerns an Opel Movano, or for any other car model. But we are here to help you. Undeniably, the origin can come from many components of the engine block, even electronic. To detect the nature of the failure of the Opel Movano, you must follow a fairly simple methodology. But before, we will see the symptoms of a slowed down idle.idle-problem-Opel-Movano

Idling problem on an Opel Movano: symptoms

Un unstable idle close to stall . This is completely the most recurring problem in slow motion. This feeling that the vehicle can stall while driving at normal speed, or that the Opel Movano grazes . It even happens that stalling occurs. In this situation, it is a real danger for the driver. If so, don't wait too long to take care of it. We suggest that you do a check via the paragraph below. We can also understand that the Opel Movano has a acceleration problem . No link in this case with a low speed problem. Losses of power and acceleration holes can happen for multiple reasons. These two different concerns should not be confused. We suggest you read our posts related to power losses.

Opel Movano: developing a diagnosis to understand the origin of idle

We have to start by performing several extremely easy checks, before going into a little more detail.

Idle of the Opel Movano: 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 your air filter is clogged. In both cases, an idle problem can occur on the Opel Movano. A White smoke comes out of the exhaust. This time again it may be due to a defect. White smoke is usually water vapor. It is therefore possible that it is an intake or cylinder head gasket problem.

Checking the engine block components

However, it is advisable to be very careful and not to tamper with the engine block connections, as this can amplify the breakdown or conceal the cause of the problem. We naturally advise you to go to a mechanic for a more in-depth audit. These are therefore step by step the constituents to check.

  • It will also be necessary to control the sensors and sensors of your engine block. It is, however, complicated to verify their proper functioning. Tutorials are easily found on youtube, and this often requires electronic devices.
  • Perform a check of pressures hydraulic. Again, the pressure tests require suitable tools.

Idle concerns are frequent, however, are complex to diagnose. A visual check on the Opel Movano makes it possible to have a clearer vision, nevertheless it is preferable not to tackle amateur DIY.
