If you have a 4 cylinder there is just one O2 sensor, it is the one just off the engine and before the catalytic converter, if you have a V6 then it is the O2 sensor in the #2 engine cylinder bank which is the driver side bank of cylinders. Also the cracked connector shell HAS TO BE REPLACED. Atrached is a link that explains all the causes of this code and possible fixes. https://www.obd-codes.com/p1151-ford
Code p 1151 refers to the heated oxygen sensor(HO2S), bank 2 running lean===causes --intake /exhaust leak/s,-- HO2S sensor bank 2 ---wiring ---ECM
replace the heated oxygen sensor ( in the exhaust manifold before the cat converter)using the correct tube spanner to avoid damage to the sensor wires
the problem of apparent in and out of drive indicates a wiring problem to the transmission in either the torque converter clutch servo/ solenoid or TCM

you probably have a vacuum leak and by the sound of it, it idles rough with the brake pedal depressed its your brake booster
