Condition A-Poor Acceleration Low Speed

The vehicle tends to have poor acceleration from a standstill. At speeds above 30-35 mph (50-55 km/h), the car may act normal. If poor acceleration is noted, it should first be determined that the exhaust system is not blocked, the engine timing is correct and the transmission is in first (1st) gear when starting out.

If the engine freely accelerates to high rpm in "Neutral" (N), it can be assumed that the engine and exhaust system are normal. Checking for poor performance in "Drive" (D) and "Reverse" (R) will help determine if the stator is freewheeling at all times.
