The 2003 Pontiac Grand Prix GT may stutter during acceleration due to several potential issues, such as a failing fuel pump, clogged fuel filter, or dirty fuel injectors, which can disrupt fuel delivery. Additionally, problems with the ignition system, including worn spark plugs or faulty ignition coils, can cause misfires that lead to stuttering. A malfunctioning throttle position sensor or issues with the transmission can also contribute to this problem. It's advisable to have the vehicle diagnosed by a mechanic to pinpoint the exact cause.
