Recently went into debt, and bought my first new Ford Ranger (not new I guess it's a 99 , still not sure why I bought a Ford) that has a fuel injected, 4 cylinder, that looks just like a Pinto 2300, that has 2 plugs per cylinder. Really runs good, but I don't understand why the 2 plugs? I was just wondering if anybody had an answer. Or if anybody has had problems with this type engine. I'm stuck in the 60-80 year range as far as engine and tech stuff.
