Can a bad O2 sensor cause hesitation?
Bad performance. Your car may misfire or experience hesitation and stalling. Most cars default to the factory air-to-fuel ratio if the oxygen sensor fails, which can cause problems because of non-standard temperature, moisture, or air composition.
How much does it cost to fix an oxygen sensor?
A brand new replacement oxygen sensor can cost you from $20 to $100, depending on the make and year of your car. Taking your car to a mechanic to fix the issue can cost up to $200. Though, this depends on the type of car and the rates of the mechanic.

Where is the oxygen sensor in the engine?
An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor. Oxygen sensors after the catalytic converter are “downstream sensors”. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios.
