Posting for a friend of mine,

What would cause extremely slow acceleration, doesn't do so until after on the gas pedal for quite some time, fuel injection test and oil checked out fine. no check engine lite.

The car sputters when trying to accelerate, fuel doesn't register as filled after doing so.

If that checks out OK then check for a clogged CAT.

Was just told that lately cheap fuel has been used alot in it. it shakes abit but idles fine in park, only in drive that it acts up. Hope this helps.

The price of the fuel used is irrelevant.
