Misfire On Two Cylinders

Been to a friends of mine shop twice to have the misfire problem fixed.  First time changed injector wires(?) for $15 and all was good.  Couple days later same thing happened and took it in where they adjusted(?) it for $0 and it ran great again.  Few days later here I am with the same thing.  Going to try and figure it out myself if I can.  Did find one tiny strange yellow wire coming out from behind the block just hanging there.  Help please.
