From: "charger_413" <charger_413@xxxx> Subject: question hey i have a question the other day my 75 gremlin started popping going done the road well first i checked for vaccum leaks found one then i discovered that the crappy chapion plug in clyninder 3 sure enough i havent put new plugs in it yet but im going to tonight my qustion is i have tons of power in 1st 2nd but i nail it in 3rd she just has no power at all - . - How many speed trans do you have - a 3 speed ? This is a standard trans or Automatic ? Your engine operates in a RPM curve - the higher the engine winds to an extent - the more power it makes. . 1st and 2nd gears are meant to accelerate the car to cruising speed - being 3rd gear - which has a lower numerical value - close to 1 to 1 for a 3sp. - one RPM of the engine . People add more gears to get acceleration further than 1st. and 2nd. A 5 speed would be nice . Look for a 1993 - '95 Ford Mustang Cobra on www.car-part.com or other locater lists. This will give you 4 acceleration gears and one cruise. Learning to read the gear ratios in transmissions and rear differential drives will give you an understanding of what combinations work best for street use or racing or strictly economy - with 6 or V8 engines Brien
