not good ! it has been awhile on one of thoes
1. it realy sounds to me like your timing belt has jumped a couple teeth and that is not good if this has happened, the valves open at the wrong time and the pistons hit the valves bending them and then you have compression.
2. that plug missing the electrode. it is very posible that it did not pass through and is stuck under a valve seat and again no compression. and that is why the car wouldn't accelerate.
3. Best advise that i can give you is pull all the plugs get a compression guage and take compression reading on all cyclinders write down your findings. but in all honisty it don't sound good(NOS) :( 8)

Yeah when it started driving sluggish for a moment and hard to accelerate it was normal and i drove for about 5 mins after that also it has done that a few time where it has acted sluggish and the service engine light flashed. The plug must have happened from repeatedly trying to start the car after the starter was replaced. I was told the timing belt might be out form the spark plug not firing in that cylinder. It's at the Ford dealer waiting to be looked at hopefully its nothing to major or too expensive otherwise it might not be worth fixing. Thanks for the advice though.
