If you got Bosch 15739, or 13989 for extended cab, or 13986 for regular cab, or Denso 234-4189 = any of these for the after catalytic converter position, you got the right one. If you got Bosch Wideband A/F oxygen sensor, part # 13613, for the before catalytic converter position, that’s the correct one, there.  
For the problems your truck is having, you need to perform a lot of performance checks on the engine, such as: fuel control system, and spark control system.
