If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.

At times, it hesitates and wants to stall. Other times it runs fine. Feels like it losses power and starts jerking.It's making me crazy as I have replaced plugs , plug wires, fuel filter, and went through transmission.
