Hi, I just bought a 2000 model and this is happening to me at the moment, it drove fine for the past day then took it onto the motorway to stretch its legs and ever since its done exactly this! I take it your Engine Management light is flashing at you? I'm going to take it back to the dealer tomorrow and see what they say about it. Will try and get OBD scan and let you know anything I find out. Is it still affecting you? Just noticed this was about a month old now. Cheers, Adam
