An engine that hesitates, stumbles or misfires when accelerating or when it is under load, is an engine that is either sucking too much air, not getting enough fuel, or misfiring. If the Check Engine Light comes on, you may find any of the following codes: P0171, P0174 Lean fuel condition codes.
Or, a defective coolant sensor may be telling the PCM the engine is colder (or warmer) than it really is. Any of these conditions can upset the fuel calibration of the engine and cause a stalling problem. Intermittent stalling can also be caused by a bad idle air bypass motor or a idle speed control motor. If these devices fail to provide the correct idle speed, the engine may die. Sometimes the fault is in the PCM or the inputs to the PCM.
