Hello, my Epica has been inactive for almost two years because it has a failure that no one has been able to solve yet. Its problem is that, when setting the first gears, revolutions raise almost to the top and then suddenly drop. When this happens, the car hits really hard; so much that, when it does, the yellow engine light turns on, not allowing me to accelerate, losing power and driving almost neutral. I need to turn it off and start the engine again so that it continues working properly. I really need some help.
