Default Pulsing feel -- advice needed

I get a pulsing staccato feel in the accelerator and sometimes steering wheel at about 70mph and up. It doesn't show until up until then, so it seems like its speed-related. And it's not always there -- sometimes smooth as silk. Sometimes it's just in the accelerator and NOT the steering wheel. Doesn't seem to be wheel or tire related since I've had alignment recently done by dealer. Any ideas or insight would be greatly appreciated.

Default alignment doesn't rule out a bent wheel at all. Most likely bent wheel 95% or flat spot on your tire

or bad CA's

wouldnt i feel the bent wheel or flat spot on tire before i hit 70mph also? it only happens at 70 and up. and it's not even a shimmy feel. it's like a high frequency pulsing.

and what are "CA's"

thanks for all the help!
