Antifreeze by spark plugs, car skipping and feels like turning off, check engine on 1995 Ford Thunderbird

Only on the left side(driver side) spark plugs (not) inside of the engine, there seems to be antifreeze on all plugs, the check engine just turned on. The car after a certain speed starts skipping and at stop lights feels like is going to turn off. I will need to replace the wires and spark plugs, but how can i fix the antifreeze from going in there and what causes this. Thanks!
