Windstar 2001 kicks when putting in drive

Winstar 2001 kicks when putting in drive 2 or 1st the reverse enters soft has codes related to oxygen sensor and one that is p1401 that I am checking if you can help me very much

Brother If you kick when putting those speeds, it is because the engine is a bit accelerated, the engine must be in at least 800 cells when we apply a speed now if it is above 1000 tends to paw since it enters with torque to the mow of mowing .. Check what the other code is the sensor of oxygen can influence the acceleration since the ECU of the car detects failure in combustion and they have to inject more fuel normal.

The rpm are normal are in 800 and yet kicks and the reverse enters all the changes they put very well
