I was surfing around at Consumer Guide auto section website and I read this:
1991 Ford Mustang: Four-cylinder engines gained two spark plugs per cylinder and 15 horsepower, now rated at 105. Convertible tops now folded closer to the body. Automatic transmissions added a brake/shift interlock.
Is it true that '91 (and I'm assuming '92-93's) 4 cylinders had two spark plugs PER cylinder? Whether its true or not I never heard that before.
*edit* sorry, It's consumer guide, not consumer report
Yeah, that's true. Think the new HEMI has that as well. It's been done on different engines since forever. More power & fewer emissions is the desired goal, with the latter being more important in recent years.
mine sounds like a turd because of the cheapo muffler that was used when it was replaced, with the crusty old tailpipe reattached to it...I gotta do someting about that. It definately sounds like a 4cyl at 3-4000 rpm
