Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Has the light come back on again or any other fault codes set?
Is it a lack of power at part throttle but you have full power when your foot is held down on the gas pedal all the way?
Let me know,thanks Pete.
On your engines throttle body is a mass air flow sensor.In some cases, this sensor becomes dirty and needs to be removed and a can of mass air flow sensor cleaner is needed to spray off the sensor to clean it.This can resolve this limp mode or lack of power at slight to part throttle.I would see if cleaning this sensor corrects the issue.
The other cause can be a failing throttle position sensor on the throttle body.If this sensor is sending a false signal this will also create this issue here.
I would have both of these checked, the mass air flow sensor cleaned and the data signals checked for the throttle position sensor at idle to wide open throttle briefly to see if the throttle position sensor needs to be replaced.You may also need to have a fuel trim relearn done with a compatible scan tool or computer plugged into your vehicle since the oxygen sensor was replaced as this sometimes has to be done.

You can try the battery disconnect but if it does not work then a scan tool with the correct software for your model would need to be used, unfortunately.
