2006 Chevy Malibu HESITATION

What's the light on the dashboard?
What does it look like?

If this is your check engine light, start by scanning your pcm for trouble codes.

It could very well explain the hesitation.

This is basically how it works: you have all kind of sensors and circuits in your car that send feedback to your car computer (PCM) at all time; when the feedback received by the pcm is not right, the computer creates a specific error code (also called DTC). This code has a certain meaning depending on what the error detected by the pcm is. Once your pcm has stored this code, it turns on your check engine light on your dash board to let you know that there is a code you need to retrieve.

Next step: scan your pcm and retrieve the code(s); that should tell you what circuit/system is not working right.

Once you get the code(s), if you need more help, just reply back and I'll do what I can. If you feel like it's too complicated, take your car to a mechanic.

Take it to Autozone they'll scan it for free and comeback with the OBD2 code/s this is where we start-Or you can try checking the items below

Possible Causes of Engine Hesitation:

Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)

Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires
