Tiembla el Motor, Un Cilindro No Funciona, Perdió Fuerza, Nissan Pick up

One cylinder is misfiring, two different causes for a Nissan Pickup 2.4L. This misfire causes a loss of power and engine vibration. In the first case, the problem was due to excess oil in the combustion chamber; the spark plug became wet with oil and the spark was no longer firing. In the second case, an injector was malfunctioning; it was lacking the signal or negative pulses from the computer.
