you need new ignition coils. The dealership just stole 500 dollars from you. Buy the coils online and install them yourself

+ 1 on that...(OEM)plugs,wires,coil,should be $250-300 and you and a buddy could put in takes about an hour. Go back and get the coils in for another 4 or 5 hundred. You could look in the DIY section and do yourself in about half an hour.
