Mechanics is a pretty logical field. However, if there is a phenomenon which is sometimes complex to explain, it is unstable idling or acceleration holes. Whether for a Toyota Hi Ace, or for any other type of automobile. However, we are here to help. Indeed, the cause can come from many components of the engine block, or even electronic ones. To find the origin of the failure of this Toyota Hi Ace, you will have to follow a fairly simple procedure. But first, let's see the symptoms of a faulty idle.
