HESITATION

1993 Oldsmobile Ciera

Engine Performance problem
1993 Oldsmobile Ciera 6 cyl Front Wheel Drive Automatic 85000 miles

Hello, I was wondering if you could help me with this. My car is in mint condition minus this problem. But when I am accerlerating from 0-10 it has a hesitation but right after that it is perfectly fine. Help please?

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

Hi Timmer did you solve this problem because I just purchased a car from a freind and it has the same problem?

No I did not, I think it has something to do with just how the car was made, if you throw some fuel injector cleaner in the gas tank when you fill up, the lag should be gone for that tank of gas but always seems to come back: (
