on the zafira theres an ignition coil block? basically instead of individual leads coming from the spark plugs theres a block that has 4 spark plug connectors that sits on top of the cylinder head and plugs straight on to the spark plugs. this can malfunction causing loss of power and severe rough running and poor starting. since 2001 my zafira has gone through 3 of them. 2 under warrenty and 1 18months ago. get this checked out.Initally they were talking about an ECU change but this is all its ever been. ECU is fine
