Sorry, this may be a stupid question. I never replace my 95 neon's spark plug. From Haynes, it seemed to me that I only need to change one spark. However, Autozone guys told me I need replace 4 sparks together. Actually, I have no idea how many sparks are in 95 neon engine (SOHC). I do appreciate if anyone who knows could tell me.
Thanks a million in advance.
