Chevrolet HHR Sensor Problem
I have a code p1174 which tells me to replace the 02 sensor which I have done but my check engine light won't go away. I've also replaced the spark plugs. Any ideas?

Fault codes never say to replace parts. They only indicate the circuit or system that needs further diagnosis. Your mechanic will connect a scanner to view live data, then watch what the oxygen sensors do in response to introducing extra fuel and extra air.
