Hi everybody, so my expedition just kicked a "P0304" code, i decided to try and check the cylinder for a bad plug or coil and noticed how extremely hard it is to access that plug, i cant seem to get a spark plug socket to grab the plug it seems it might be broken with pieces inside but i cant really see for sure, is there any way to remove the windshield wiper cowl or other parts to make it more easier to access the back plugs?
