Expert:  Dan replied 1 year ago.

o2 sensor code could mean a few different things. It could be a faulty sensor, or there could be a separate problem that is causing the o2 sensor to set the code and the sensor could be ok.

vacuum leaks, misfires, fuel problems.

Try doing the key dance to get the codes. Turn key on, off, on, off, on, off then leave on. Look at the odometer display, the code will be displayed for a few seconds and will say done, when finished.

Usually a hesitation that does not set any codes is fuel related. Check fuel pressure with a gauge. Drive and monitor fuel pressure when it happens. You could have a bad fuel filter.

Also check for vacuum leaks, you could spray carb cleaner on vacuum hoses and around the intake, check for any change in rpm indicating a leak.
