It began like this
One morning I started my car i notice it wasn't idling properly. When I drove out i realized the power has been significanly cut. I went to a friend of mine and we switched coilpacks one by one to diagnose which cylinder was not firing. Found out it was cylinder 1.
We switched in an old coilpack and it was good to go.
ONE WEEK LATER AND THE PROBLEM IS BACK. HELP!!
WHAT IS KILLING THE COILPACK??
Or could it be something else?
