Since a rich condition robs a vehicle of power, a bad oxygen sensor can cause poor acceleration. If your vehicle is running rich, replace the oxygen sensor to see if that solves the problem. While the oxygen sensor can indeed cause an engine to run poorly, slow acceleration could also be a clogged catalytic converter, or CAT.
Can O2 sensor affect acceleration?
While the oxygen sensor can indeed cause an engine to run poorly, slow acceleration could also be a clogged catalytic converter, or CAT. Over time they clog up and cease to work properly, which can result in poor acceleration, an erratic idle and failed emissions tests.
What can cause sluggish acceleration?
Hiccups in air and fuel delivery and sensor issues
Why did my car suddenly stop accelerating?
There are many reasons why your vehicle may be losing power, especially when accelerating. Some of these common causes are: Mechanical problems such as: Low compression, clogged fuel filter, dirty air filter, clogged Exhaust Manifold. Malfunction of actuators such as: Bad injectors, bad fuel pump, bad spark plugs.

Will bad O2 sensor affect gas mileage?
Having bad oxygen sensors and air filters can reduce your gas mileage by up to 20%. The oxygen sensors help keep the proper mixture of air and fuel, and having this off balance can be inefficient. If they misfire, or are working poorly, this can affect your gas mileage in a negative way.
Is oxygen sensor same as mass air flow sensor?
some ppl call the Mass Airflow(MAF) sensor as O2 sensor as well, that's why TS is confused. O2 sensors are present on both the air intake and exhaust side. For intake side they are called MAF sensor.
