Today I did an oil change, change both my fuel filter, clean my drop in AFE PRO DRY 7 air filter, & put 2 new rear tires. But now while I have my truck idling I feel a little vibration thur the steering wheel, but if I drive or park & increase the RPM, the vibration is gone. COULD the problem be the fuel filter ???

 

mine was doing that, the balancing weight on my crankshaft was slightly off. check yours out.
