Not running on all cylinders? Bad plugs, wires, or valve? Try a compression test to see if problem is internal to the engine
Its your coil packs, they become defective after time, it causes a sputtering and loss of compression. Also check the intkae manifold. the throttle body control will regulate fuel to stop sputtering set idle for around 900rpms

I sometimes sputter when I'm nervous. Please reword the question and tell me what year and engine and describe what you are doing with the car when "sputtering" occurs. Would help if you can think of additional description of what you mean by "sputtering".
probably the O RING which is located under the spigot swivel
There are several things that can cause an engine to quit when you open the throttle. A poorly adjusted carburetor, and poor airflow through the air intake system are two common causes.

check plugs &wires
plugged cat, but make sure you check your spark plugs and wires. If its time to change them , then change them first and drive the car. , if sputtering continues, check the cat and the ignition coil.
fuel pressure regulator or the injection of the fuel
what causes my thunsercat to jerk in all gears on a steady throttle?
Sputtering engine may be caused by one or more faulty components. It may be from spark plugs, spark plug wires, distributor cap and rotor. Similar faulty component affecting the air-fuel mixture like a bad oxygen sensor, throttle position sensor or engine temperature sensor.
The electronic throttle control light stays on when the engine computer detects a malfunction related to the throttle system. You need to have the system checked for codes to know possible causes.
