Poor Acceleration at Low Speed
WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
If the stator is freewheeling at all times, the car tends to have poor acceleration from a standstill. At speeds above 50-55 km/h (30-35 mph), the car may perform normally. For poor acceleration, you should first determine that the exhaust system is not blocked, and the transmission is in FIRST range when starting out.
If the engine freely accelerates to a high RPM in NEUTRAL, you can assume that the engine and the exhaust system are normal. Inspect for poor performance in DRIVE and REVERSE in order to help determine if the stator is freewheeling at all times.
