Do I have to replace all six coil packs?
My check engine light is on and I had it hooked up to a computer to find out what it said was wrong. It showed that one of my coil packs is messed up. The guy who did this said that if one goes bad, I'll have to replace all six. Is that true?
Yes, it's recommended to replace all the coils at the same time -
