So lately in my 4.6 ive been experiencing weird acceleration patterns that seem to happen not very often (once ever few days) but still brings me concern. The issue is that some times when i step on the gas the car will shake and hesitate to accelerate, but its not a dying sputter. It feels more like the car is having a hard time changing gears. I wish I could explain it a little better, but is this something you would be concerned about?

Car shaking should not be the trans. Sounds like an engine misfire of some sort.

Just replaced the wires 2 months ago. But I will look into a possible misfire.
Motorcraft wires I hope?

I remember RobertP telling me to insulate any wires that cross the huge harness that runs near the right valve cover. I have a rubber hose wrapped around one spark plug wire where it rests on that harness.

Doesn't hurt to make sure all the wire separators are in place, and double check they are all fully pushed on the plugs.

I would slap a set of Motorcrafts on there. Motorcraft for everything, especially electrical.
