[QUOTE="wingzee, post: 657078, member: 22730"] Just to share with the rest on how to detect a potential faulty coil: GT1: Running value for cylinders, prior to replacement of faulty coil on cylinder 4 (do take note of any values which shown a huge variance with the rest, may point to a faulty coil). In my case, it was shown that cylinder 4's values is way off from the rest.

Can anyone assist to interpret these results? Are these normal?
