Focus Misfire

[anthony25]

hi everyone,so my wife collected me from work today,drove along 30mph car developed a misfire,got home removed ignition leads to see spark plug wells filled with oil,cleaned it all out cleaned plugs and so on,started car up,misfire even worseand now eml light has come on,with the car at idle i removed each lead from left to right no spark from 2 or 3 at all....i suspect coil pack here,as always all help appreciated.

Probably is a couple of dodgy coil packs causing the misfire, and the plug wells have probably filled with oil due to a leaky cam / rocker cover gasket.
To be sure about whether it's a dodgy coil pack you'll have to get the car plugged into a diagnostics computer.
