Rmv plug & coil frm #6 to chk for wear. Placed bk intact. Motor now runs rough

What is your question?

Put new plug & coil in #6. Motor runs rough, shifts rough. Car was fine before this. Also, disconnected connection to coil while motor running. Saw additional loss of power. Autozone says scan shows misfire in #5!!! How cld this procedure affect opposite cylinder!? DIC shows Service Stabilitrak and Traction Control systems. Should I put old plug and coil in cylinder #5??? Thx
