Code P1131 & P1132 after headswap

[97GTSTANG]

Update after headswap, car runs great and thanks for Willie from dirtydirtyracing. The mail tune he sent with the SCT made a world of difference. Thanks for all the help and answering all my questions.

Before the tune, i was pulling code 1131, after tune now its pulling 1132. I want to start first with the o2 sensor. The car was sitting for 8 months before the headswap, so maybe the 02sensor went bad. I was advised to start with the front 2 sensors.

Are these the correct ones? And i will need 2 correct? The car runs very well and i have read that usually when an 02 sensor is bad the car doesnt run very well at all. Any other suggestions? Thanks for all your help

If you have long tubes, recommending staying with Ford O2 sensors.

What have you done to rule out the other "usual" causes for this DTC?

Both codes are for the same O2 sensor (Right front). So you could get by with replacing just the sensor called out.
