Mechanics is a fairly logical job. However if there is a problem that is sometimes hard to understand, it is an unstable idle or acceleration holes. Whether it concerns a Toyota Corolla 5, or any model of vehicle. However, we can help you understand. Indeed, the origin can come from a large number of engine components, even electronic.
