Alright, changed oil on my 06 SCREW 5.4 and started it up for a few minutes to idle. Drove it and it's shaking while driving and dieseling here and there while idling. Was perfect before change. Any ideas here guys? Maybe too much oil? Checked before I left for work but was kind of in a hurry. Appreciate any help or ideas.

Oh and while I idled after changing, it sounded better than ever up until I drove it.
