i have a 1990 coupe quattro with a 10v NG engine, it cuts out when ever it wants but allways starts again anytime from 2 min to 2 hours, there is no reason to it cutting out, it could be cold or hot high revs low revs. i have checked as much as i can and cannot find the problem i have changed the battery and coil and leads. any help would be most appreciated
thanks
mike
