加速问题

早安朋友。
I just acquired a Ford Ranger truck 2600 motor cabin, peeked in Colombia by the Mazda, so it carries the same Mazda engine, the problem is that when I turn on the car in the morning it takes a bit to turn on it either cold or hot is the same, the other problem is that walking the first or second one, the engine is very accelerated and does not take speed new speed in third Engine and puts the engine at a thousand revolutions at a thousand革命，我想降低加速电缆旁边的螺钉的加速度，但不会降低旋转，这就是使我花费大量燃料的原因。
事先感谢他们提供的任何帮助，我一直在寻找某种类型的电动机手册，如果有人有促进它会非常感激，我找不到它。
