Hi dbanks12

After you replaced the O2 sensor did you erase the codes ? When replacing a sensor it is always a good idea to erase the codes. To do this, disconnect the battery for 5 min. The problem with that sometimes is that the settings for transmission ( cars equiped with transmission ECM) also get lost causing drivability issues. To correct it, the car has to be driven for several kilometers in order to re-set the ECM.
