We're having problems with an intermittent misfire on the car (2 litre T16
Rover; 10:1 comp, Elec fuel/ignition, map based, 140hp), and I've done all I
can think to do. Does it regardless of engine temp, ambient temp, load,
angle the car is at, revs.... One minute its fine, the next it misfires, a
cackle a pop and a BANG later and its blown the back box to pieces.
