Hi. Just bought my first Alfa, 166 2.5 V6 Steptronic. 48k miles. It drives superb apart from one problem. When I push the accelrator past the halfway mark it sort of stutters and looses power. It could be misfiring or "flooding". Not sure. I am not too technical. Apart from that everything fine. Cruises very well at 80 mph if you are patient to get there. Overtaking takes planning as pushing the accelerator to the floor has the opposite effect. Any ideas please? I am not too technical but can try a few things. Would mostly like to have a more informed idea before taking to garage.
