O2 problem

[hendrixvodu]

ok so i have an 84 m10 with the single wire sensor, replaced the sensor and the car continues to buck and idle very badly....its a new bosh o2 sensor.. so i unplug the unit and the car is perfectly fine, the problem just disappears. plug it back in and the problem is back again......i may add that it did it last year and ran it the summer without one. i plugged it back in over the winter....the car ran perfectly fine with it in and them 5 mins later started again! ...any idea what so ever guys?! i need input big time!

thanks

did you touch the front of the o2 sensor with your hands? or get anything on the o2 sensor?
