Hesitation upon acceleration in a 2003 Saturn Vue 4 Cylinder Automatic

When starting cold the Vue has a brief 2-4 second period of no acceleration out of the garage or for the first few stop signs within the first 1/2 mile. As the gas pedal is pushed to slowly accelerate, the car pauses as rpms decrease the car never stalls out. After the brief period of “no acceleration” the car accelerates in a normal fashion. Once warm the car never has this “hesitation.”

Here are 4 suggestions.

  1. Ignition system not operating properly.
  2. Clogged or dirty fuel injectors
  3. Low fuel pressure. (Perhaps the fuel filter is dirty or the fuel regulator is faulty)
    4)Emissions or engine control system components faulty.

I had the same thing on my Vue but it didn’t happen often. I traded it. I call it the GM computer glitch but I didn’t try to find out what caused it.
