yeah the header o2 sensors are actually factory widebands so i hope you installed a five wire wideband sensor instead of a five wire narrow band. what was the brand and part number of the sensor you bought? if you only have the store p/n tell us where you bought it from as well. i'll look it up for you and double check it with the manual. any chance of getting the output voltage reading?

edit: also check for gasket leaks and header bolts that have loosened up. i always get the car up to heat with a hard drive let it cool and retorque the bolts thenext day as they like to come loose. if you're getting air in there it would rn excessivly rich
