Mechanics is a fairly logical field. But if there is one problem that is sometimes hard to explain, it's unstable idle or throttle holes. Whether it concerns a Renault Espace 2, or any other car model. But we're here to help. Undeniably, the cause can come from a large number of components of the engine block, or even electronics. To find the origin of the Renault Espace 2 failure, you have to follow a strict method. But first, let's see the signs of a poor idle.
Idling problem on a Renault Espace 2: symptoms
Un unstable idle close to stall . This is really the most common slow motion problem. This impression that the vehicle will stall while driving at a normal pace, or that the Renault Espace 2 grazes .
