Poor Acceleration At Low Speed

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.
