Powdery stuff in number one coil, just dust or corrosion? Get a torch deep down inside and check contacts In the end.
Clean up spark plug threads and contact with a tooth brush sized brass brush. They do get a certain amount of surface corrosion over the years but have to be very bad to cause no spark /misfire issues on a regular town car.
Some powder, but didn’t seem like corrosion. Number one is closest to the outside world, so figured it was from a dusty road or similar. Blew it out and popped it back. I couldn’t make it stutter when driving it but I’ll take it out of town at the weekend for a proper drive.
