Hey All,

My '06 4.4 is shaking on startup. So far it's happened twice when it's cold out and the second time the "Check Engine" light came on. After reving the engine a bit the shaking goes away and the X runs smoth (check engine light stays on). I ended up dropping it off at the shop anyways for them to take a look at it.

Any ideas what I should expect from the shop?
