Problem is likely to be electrical controls. The sluggish acceleration indicates the trans is not down shifting. It most probably is stuck in 3rd gear.
This indicates an error has occurred and the transmission control system has gone into limp mode.
Get a free scan done at Autozone to see if they can retrieve any trouble codes. Let me know the exact trouble code if any found.
If none found, meybe you can try some DIY test by retrieveing the trouble codes manually.
