I am told by Checker Auto there are 2 separate 02 sensors on this car but I'm unable to find one of them. The one I did find is on the exhaust manifold between the engine and the firewall. They tell me the other one is located after the catalytic convertor. Does this sound plausible? Any help would be much appreciated, thank you. Alan

What model is this-Cutlass Ciera has (1) on the exhaust manifold-who knows you might be right only having one-but won't hurt to go underneath to check

The car's an "87 Olds delta 88 royale. I've looked under the vehicle and cannot find that second 02 sensor. I don't think there is one. Thanks for your input, Alan.
