Those were recalled for blowing the spark plugs out of the heads. Also, the plugs have a habit for breaking as well. Might be one of those issues.

Is it throwing the engine light? If so, you cand find out exactly which cylinder(s) are misfiring. What I did on my 99 crown vic police intercept to find which coil is bad, I started the car and unplugged one coil at a time. If it starts running worse when you unplug one, its a good coil. No difference, its bad. You could have one or more plugs fouled out too. Try that and see what you find.
