MasterIf it was an O2 sensor code that was stored initially make sure the part number of the parts you fitted are correct and the right sensors are in the right positions. Is there a Check Engine Light on now, if so scan to determine which codes are now present. Check to see that vacuum hoses or electrical connectors were not inadvertently knocked off during sensor replacement.
