ok well i checked my ignition system for sparks today and it turns out that only my top two plugs are getting spark... my bottom two are not...so i checked my coils and the coil closest to the back of the engine bay is not giving a spark? do i have to replace it or is this a common thing that can be fixed?

 

It usually means you have a faulty ignitor. You can determine this be swapping the ignitors around and seeing if you have spark on the opposite plugs.

 

alright, thanks
