Re: 1990 Ranger 2.3L Dual Spark plugs? (8)
Ahhhh the 2.3. That is what i am driving right now and to the best of my limited knowledge the reason for the dual spark plugs is to increase fuel economy and provide a smother running vehicle. But i could be mistaken it might actually be used to prevent Satan from returning to the earth. But i know one thing it is always funny to see peoples expression when you tell them it is a 4 cyl. with 8 plugs.
----------
oh and they also act as backup plugs..... the truck can run not well but can run with only 4 plugs 1 per cylinder
