The cause of engine stutter could lead to several things. Fuel, air and spark.
But first connect your vehicle to a computer scanner to make sure it is not a faulty sensor causing all the problems.
Most of the time, a stuttering engine is due to something wrong with the fuel system. I.E.-- Fuel pump, filter, fuel pressure regulator or a short or open on a fuel injector.
Check vacuum using a vacuum gauge. And while you are checking the wires and plugs you might as well do a compression test as well.
You must also check the spark. Is your ignition coil good? how old is it? how are the conditions of the wires (outside and connecting ends) Many times a spark plug wire will look fine and new until you touch it and it gives you the shock of your life. Spark plugs should also be checked. While checking the spark plugs
do compression test. Low compression as well as a damaged harmonic balancer can cause stutter as well.
Does it stop stuttering when you accelerate. 9/10 times it is the fuel.
So remember to do it in this order so you can save time and money.
1-scanner
2-vacuum
3-fuel pressure etc...
4- wire connections as well as plugs.
