Forward/backward 'slop'

[epapp]

I have some slop. I chocked it up to the front engine mount so I replaced it. The slop is a tiny bit better, but the source of such slop was obviously not the front mount.

When I am releasing the clutch in 1st gear from a standstill, everything is nice and tight with my new clutch and engine mount. The slop is felt when I let off the throttle. Its like the car can roll 'freely' for maybe 1.5 inches of road before I can feel the can begin to engine break. Besides gear slop, what could this be?

On a side note, I have also noticed if I am rolling slowly in neutral and apply the hand break gracefully, I will notice a similar sort of 'slop' where the hand break will catch but the car will roll just a bit more before beginning to slow. Maybe related?
