COIL PACK PROBLEM
 

Can anybody tell me if i can substitute a Diamond fk0140 coil pack with a Diamond FK0186, any help would be appreciated, this will be my fourth coil pack i have already changed the position switch as well it runs a little better each time a new part is fitted but im still not happy with the performance it continually feels like it is holding back,which can be pretty annoying at times,well most of the time. Cheers.:cry:
