What causes 1993 4 Runner to be slow to engage into gear when starting from stop

What is your question?

1993 4 Runner is slow to engage into gear after starting from a stopped position - stop sign, stop light etc. When the accelerator is depressed the engine will rev until the car begins to slowly move forward and the vehicle begins to finally reach desired speed and will operate fine until vehicle slows down to a stop and then repeats. Not all the time but at this point off and on. Vehicle does not lurch or make any noise when speed catches up with speed. Thank you for your help !!!

What makes this problem better or worse?

Starting out from a start problem begins until finally engages
