Don’t drive the car while it’s misfiring. It can damage to the engine over time.

You can grease the inside of part D or Where E would start. Not the shaft. It’s a sealing surface to keep water out of the spark plug well. Do it lightly, just to get it to slide down.

Don’t grease part A. They were using boot grease or dielectric grease. It causes problems and isn’t necessary with the new technology. (It’s good for old school cap and rotor systems. )

You’ll know when it’s all the way down and facing the right direction.
