Is it a dead miss or random?

Random generally under light to moderate acceleration. Just pulled original injectors back out cleaned and resealed all of them same thing. As it gets hot, seems to get better. Temp gauge still dead 0 but swapped original temp sensor and switch back in and error 51 code is gone. Still missing.

Random and not consistent doesn't make things any easier.

Did you use Motorcraft or Autolite plugs? Have taken a look at them since you changed injectors?
