If your not getting spark from 1 and 4 your sure of that and you swapped the coils that were sparking then more then likely you have a bad icm. The cps would not just take out two cylinders spark like that it would take out all four of them. Do you have a pick a part around you were you can pull your own used car parts?Those modules dont fail often and I would put a used one on my car even.
