my s2 has been parked up for a couple of weeks jump in it last weekend and the cars started to miss,more at low down revs and fine at higher revs,then every now and again i would get to around 3000 rpm hold back like mad and sound like a subaru.

new parts fitted so far =
4x new plugs 071 ford
1x set of motorsport leads
new group A coil
new rota arm and cap
the cars running standard boost around 9psi with no mods,ticks over fine ,starts fine and no oil or fuel leaks.
still the car was the same,checked the timing and was slightly out around 6 btdc, set this to 12 btdc,i little better but still missing and holding back.when i got the new plugs i set the gap at 1mm,with the group A coil i was told to increase the gap to 1.1 mm,still no better.so i tried the gap down to 0.6mm .the cars alot better with only i slight miss at low revs but now pulls fine.could this be the sign of the dizzy failing? sending a weak spark?
