Ok got a 1.8t s line and it started losing power going up hills the other day and the next day it would start but stall while idling. If I put it in gear and try starting it it won't start but when in neutral I can keep it running by revving it although a little lumpy. I took the cat of and checked that as someone said it may be blocked. Also I changed all 4 coil packs today but with no difference. It is running quite rich and my spark plugs were black when I cleaned them earlier. Any help would be much appreciated or better still if any one knows a gd mechanic near Taunton in Somerset to come sort it?
