I've been told you should use the OEM sensors. (Probably just the plug that's different) I was going to use a Bosch, but ended up using a Subaru one when i had a P0037 (rear 02) and CEL cleared no worries and didn't come back.
Where did you fit the o2 sensor?
It could be the front afr sensor on the headers for your my03?
