As far as the coils are concerned, they are not hard to replace. You will need to remove the cover from the top of the engine to gain access. Each cylinder has its own coil, so make sure you replace the correct ones.
Additionally, make sure the spark plug wires are not damaged in any way.
If you look below, I attached the directions for replacement. Take a look through them and let me know if this helps or if you have questions.
