hello everyone, i have an audi a4 1.8t sport on an 03 plate. this problem started a while ago, while driving or on idle the engine stutters! it started every now and again and i thought it was my driving but this problem has got worse, much worse over the last day to the point where i think its going to conk out. it seems worse at low revs and on hills when setting off, also seems to be worse when the engine is getting warmer. the reason for this is the engine management light has come on, i have read something about the ignition coils might be the problem but could do with some help! please!!!!!! thanks.
