Hi, my vehicle suddenly chokes and loses power. When this happens, the orange light indicating an engine failure turns on and, after a couple of seconds, it disappears and the vehicle starts working properly again. Occasionally, the engine stalls suddenly as well.
Almost all Vectras have a power loss and turbo failures, it is a manufacturing problem. It is usually said that it is a valve that fails and causes the problem, but it is not. The real cause is the dirtiness in the intake manifold.
