Question about 2000 Mercury Grand Marquis
The engine starts to skip at 40mph? Had a diagnostic test done, found one spark plug that neede replacing, but problem return that?
If the moisture was on the outside of the plug most likely water got into the hole. this causes high stress on the coil and causes them to break down. If the plug was replaced and the symptom returned
i would replace the coil.
