Engine Mechanical problem
2002 Ford Taurus 6 cyl Two Wheel Drive Automatic 88000 miles

If I need to accerlate to pass a car my taurus cuts out /surges. Its kind of scarey. If you back off a bit it will pick back up and go.
other than that it runs great. It has a 3.0 vulcan 6 cyl. I have changed the fuel filter, spark plugs. Any other ideas would be great!

thanks

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
