Wierd Vibration

[xTOM153x]

I have no clue what this is its been doing it since i got the truck which has been a year now but you notice it most at idle I have a strong vibration thats felt throughout the vehicle I noticed it more after I put in a new fuel filter. RPMS are showing no indication of the symptoms because they stay a steady 900rpm throughout at idle. If it helps at all it feels like its going to stall when taking off from a stop with this vibration but it is showing no indication of it on the tachometer.

turn the car off, and stick your finger in the crank hole, can you move something around in there, if so you need a new crank pulley.

replaced the plugs and wires because I had to pretty soon anyway seemed one of the wires was completely shot at the end it disintegrated in my hand. The truck runs brand new now after the new plugs and wires and the vibration is gone
