1. Or AC/Delco Double Platinum #41-993 factory pre-gapped at .060.
3. This has been discussed many, many times. Please use the 'search' function for '#3 spark plug', etc. |

wow how do you tell what one is bad then ? or do replace them all there like 60 bucks a pop

Just to clarify, a '97 will likely have four (4) O2 sensors.
If you do need to replace an O2 sensor, use AC Delco sensors only. In my experience, AC Delco sensors last longer than others. But do diagnose the problem first. It is never a good idea to just throw parts at a problem. |
