Turns out 2 coil packs were almost dead and the gap in my plugs were off. Bought new coils and Plugs from super cheap and the car ran worse! Misfired beond beliefe after 4000 rpm. Changed back to old plugs and she ran much better. Turns out that they have me standard ba plugs with a 1.3mm gap when I need .8mm. All sorted now! Thanks for you advise guys! Much appreciated!

Especially a BA, trust me I know..
