Help V6 02 Camaro

[02Neon]

Engine runs ruff, stumbles, will not pull away easy, sounds like a 4 instead of a six, new plugs,wires, fuel filter.. Son had it checked at Auto zone no code.
I am old school, points, carb's. If it was my old chevy I would say dirty carb or fuel pump. , This car is an 02 40K miles V6 auto.. Any suggestion or help will be appreciated
