Ford Repair: F150 V8 302 ignition, ford dealer, fuel filter

Question
engine shakes the entire vehicle when accelerating up to 2000 rpm. Ford dealer replaced 2 coil packs and said plugs are wet with fuel when checked...but no improvement in operation. Any suggestions appreciated.

Answer
I would appreciate the year of the truck please? Is the check engine light on? If so, have the codes read for free at your nearest parts store. Try it even if the light isn't on. Occasionally, a code will still be stored. My first guess, not knowing the year, which limits me would be to replace the fuel filter. Replace it, see if it fixes the problem, if not, tell me the year model please. Thanks.
