hesitation

O2 sensor problems will ususally happen constant at high speed/ high load conditions.
Intermittent hesitation could be the afm, or the tps, but should have a code pop up with te and e1 shorted. Could also be fuel pressure problem. Resistance checks might show all good unless you can test it when it is hesitating, which would be difficult at best.
