Replace ignition coil.

I have same problem now. Please advice with my Peugeot 207 1.6 VTi. The engine was running on 3 cylinders, I changed the coil and the next day it only runs on 3 cylinders again...

What code is the scanner giving you, does the check engine light come on, and did you clear the code after replacing the coil
