Been experiencing misfires etc when putting the car under load.

It pointed to the usual suspects.

.

.dizzy/rotor/plugs.

Checked dizzy and it looks shot.

.heavy deposits on all 4 contacts.

So im ordering new items of all three.

The wierd thing was.

.when I started my car

(a very troubled start I should add)the idle was as usual lumpy BUT when I stabbed the throttle the engine revs dropped to 200rpm and went very quiete.

.

.

.and all I could hear was my induction kit sucking in air and the boost gauge winding up and down from 0

to 1.5 Bar! AND the revs moving up to 2000rpm and down to 200rpm all on its own without me touching the throttle! WTF?! Looking back at it it was pretty comedy.

Questions:
What the hell would cause this reaction from the car?

Also is it normal for dizzys to be eaten in 12 months?
