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.

Sounds like you have a misfire problem. Here is an article about misfires to help explain what it is : http://repairpal.com/misfire-what-does-it-mean
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.
