Failure on a plate

I have a problem on a plate does not get the land signal that handles the computer for injector 1 and for coil 1 and 4 I reviewed continuity and everything well connected the harness and work well the car since its failure was that it had no strength sat down when accelerating as if it were late back but the time band is well synchronized and I suddenly had the fault to present the fault and the codes appear. P0351 will be thanks
