Hey
It turns out my fan is working fine.
Its been around 2 weeks or so since my last post, I purchased another 6 Denso coils for cheap off somebody, and the car was working fine for the last 2 weeks, what I also noticed is that when the ignition coils are working well, the thermometer never goes over the halfway point, so it seems it may not be the heat that's degrading the coils, seems more like as the coils fail, the engine begins to run on less cylinders and this is what maybe creating the heat.
Any ideas as to what could be killing the coils if its not the heat?
Kind regards
