Today, I noticed that my motor started to stutter during normal driving. I have a feeling it is fuel related but not really sure. So today I purchased a fuel system cleaner and did that, and also replaced the spark plugs and wires. It stilll happens.

What could it be? I am next thinking fuel pump and fuel filter. What are your thoughts?

Thank you.

Does it do this during a certain RPM range, or all over the place? Is it sporadic or constant? What year/model/engine?

Usually at low RPMs. Sporadic and it's a 1998 GSR motor.

stop throwing parts at your car and diagnose your problem properly itll save u money.
