Hiya lads
Need pointing in the right direction with my car. Got an is 200 sport 03 and engine management light is on! Got a diagnostic and came up as air and fuel mixture, can't remember the code! When driving round town etc the car runs fine but when I'm in a gear for a while ie on the motorway the car suddenly loses power and the engine noise deepens! But when I stop the car put it in 1st and drive off it's fine again?? Any ideas??
