Customer Question

I have a 2010 Toyota prius with 161,000 miles on it and the idle gets rough at cold idle but not as much when warm if at all. I was told by the Toyota dealership that I was having a misfire on number 1 and 4 cylinder. So being mechanically inclined I replaced all four ignition coils and still have the same problem. Can you help me please?
