Hello kaisero, see if this happens to you that your H1 is equipped with a turbocharum, now if you stop official you would have to check the electrical system I bone the wiring of this if everything is ok, you will have to change it are not very expensive and sell kit to install them is relatively easy to perform this task, check the relay if you possess it but the fuse, the fuse must Autodetion, they are generally focused on a deterioration of the Turvo and its breakdown, you can decrease this risk in a simple but uncomfortable way, make the vehicle stop the vehicle you have to leave it in relief 1 minute or until the Turvo stops or its revolutions fall, it is that for the moment the Timer changes and this is already faster and less problematic.
