Tune up spark plugs and wires check Trans fluid if that doesn't work u might need a new timing chain

like said in the above post. a tune up is recommended, the the spark plugs and wires replaced check your fluids, make sure your filter is good or replace it , inspect the throttle body as well could be an issue with a cable maybe something interfering or a throttle position sensor could be it as well. sounds like it could be a transmission issue, check your fluids and i also recommend the lucas gear slip fix additive for the transmission fluid. hope this helps you resolve your issue.
