mechanical problem

I have a problem with my Ford Ranger 98 2.5lts Starting problems the car turns on but not kept told me that they were the injectors but I do not know what it will be or may be helped

When the car starts and keeping them accelerating them, it continues to be extinguished or remains accelerated or in pesa ahuantar and does not accelerate because it can be gasoline system or gasoline pump if it is maintained and accelerates normal but when you lower it to its minimum crankshaft I already spend with a mitsubishi grandis chartio the car endures by accelerating and did not scare the minimum and the sensor had a signal escape

My caroo still accelerating it went to explosion and went out
