why is it shaking and hesitating when accelerating. on 2000 Ford Expedition

It shakes everytime you push on the gas, and quits when you don't. sometimes it will shake when sitting there. Idols higher than normal. running pretty rough now.

Go on Ebay and get an aftermarket set. I bought 8 coils for $57.00 (free shipping); bought my plugs locally and found a mechanic to install them for $45.00. My Exp. did the same thing...it wasn't burning all the fuel. Get them all replaced at the same time or it will throw the computor off.
