Poor Acceleration At Low Speed
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2002 GMC Savana Special, 2002 GMC Savana Camper Special, 2002 GMC Savana, 2002 Chevrolet RV Cutaway, and 2002 Chevrolet Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
If the stator is freewheeling at all times, the vehicle tends to have poor acceleration from a standstill. At speeds above 30-35 MPH, the vehicle may act normally. For poor acceleration, you should first determine that the exhaust system is not blocked, and the transmission is in 1st gear when starting out.
If the engine freely accelerates to high RPM in Neutral, you can assume that the engine and the exhaust system are normal. Check for poor performance in Drive and Reverse to help determine if the stator is freewheeling at all times.
