Car Pulses during accel and cruising?

Yeah, so here I am yet AGAIN.

I have figured out EVERYTHING except fo this stupid problem on my car.

When I drive on the highway, i get this constant thub thub thub thub type of sound... however, it seems to be constant, and even happens at a simmilar rate when I'm accelerating from a stop as well, cruising at 3000 rpm in 4th, etc...

So far I've done this:

AFM
TPS
Driveshaft
New rear tires

That got rid of everything but this problem. It's not significant enough to where I cant drive the car, but it is annoying as all hell. I've tried to diagnose it to no avail... help please.
