I have Opel zafira 2002 2.0 for some time when the car warms up, the emergency mode starts and when it is stretched to over 2000 thousand revolutions. This emergency mode turns off and when I turn on the gas, for example, before an intersection, it turns on again. Emergency mode. What can it be a mechanic spreads his hands (it's not egr and the hoses are also good) HELP.
