Hi everyone, I have a 2000 mustang gt convertible. My car was missing and the check engine light was on. I took the car to ford and they diagnosed the #5 and 6 coil as malfunctioning and needing replacement. I looked at the #5 coil and it had a hole in the top of it like it melted. I put a new neihoff coil in and about thirty seconds after I started the vehicle the car filled with smoke and when I lifted the hood the 50 dollar coil had burnt in the same way as the stock one almost instantly. I also at the same time replaced all the spark plugs and coil boots. Any ideas on what's frying the coil?
