I need help! I have a 1996 Olds Achieva. I only have 1 car and its acting up.

I need this car to get back and forth to work. The car has a miss. I changed the fuel pump, changed the
spark plugs and still have the miss. Can anyone help or give me ideas what it can be?

When i start off or come to a stop it takes a sec seconds longer than it should to get up to speed. Once at 40 - 45 miles and hour I can stay there as long as I dont have to slow down or stop.
