So after replacing both O2 sensors two weeks ago, my "check engine" light is still coming on 10 - 15 mins after start-up. The funny thing about it is that the display under the passenger seat is black, no codes are lit up. I know the display works, just got codes coming up for the O2 senors, hence the replacement.
Any thoughts??? Could the timing being not set correctly cause this? Or maybe a vacuum leak?
