i have been driving around with the check engine light on for awhile now. i did a 98 b18b into my 00 EK with an obd2b to obd2a jumper harness. after the swap i jump the code and got code 41 one which i think is the heated o2 sensor circuit. is this hurting my performance? does anyone know how to get rid of the code without converting back to obd1? Please help.

 

I just pulled codes and the ecu was only throwing a code 41. Just curious if you fixed the problem or figured out a way to eliminate the code?
