ok, the car was fine, till i put on borla headers. now i get that annoying check engine light. i have an idea that it could be the o2 sensors acting up. i also know that there was a recall on the o2 sensors for MY00 and down. would there be a recall for MY 01? also is there a way for a permanent fix on that check engine light. i have already reseted the ecu twice, but the light comes back. now i just leave it alone hoping it goes away. any help would rally be appreciated.
