have you connected them correctly...

if so

swap back to the originals and see if that cures the problem..

yeah thing is i put the originals back on and the car runs fine? im sure im connecting them in the right order as i just followed the locations of the originals. not sure wether the leads are faulty or im doing something wrong?

Unless they aren't seating correctly they must be faulty... I''d stick with the o/e items

Sounds weird mate, although I had a problem with my leads. Not quite high performance but hey were bosch and one of mine were faulty and caused the car to missfire etc. The fact the might be faulty could be a possibility especially if you were able to connect the others again and the car ran fine on them?
