That's good to know because my heart dropped after seeing the price of the coils.My car used to throw codes for misfires of all cyls when spark plugs needed replacement. The coils in these cars rarely fail. I would just get a new set of NGK Laser Iridium plugs and clear the codes. Then see what you get. Beware of eBay or Amazon for plugs. I'd stick to local parts stores or Rock Auto.
