What are some signs of a bad oxygen sensor??

 

Poor gas milage and running rich....

 

Sometimes when you give it partial throttle it will hesitate and the motor will shake sometimes when cruising (noticable in 6 speed when shifter shakes more than normal)

 

horrible horrible things, that's what. At least for me. I had something wrong with one or both o2s and the car was so bad to drive i wished i had a pinto instead of the T/A to drive. It would cause the engine to constantly cutout while driving.
