The code indicates cylinder 4 is misfiring and from what I read, Ford has a problem that they didn't recall on this engine with the coolant leaking into the cylinder. Mine has 98000 miles and just started to have the check engine light come on and the symptom's of misfiring starting in the engine. I plan on replacing the spark plugs and Ignition Coil this week, but how long before these symptom's occur again, and should I be looking to sell the car and get another one?

are you losing coolant?

that depends on what is causing them. You need to diagnose the problem. Throwing parts at it isn't a great way. Check out our misfire topic in the FAQ.
