hi guys! my engine light has been on for a while and i recently had someone test it to see why it was coming on. i was told it was 2, CO2 sensors that are going off. two days later my fuel pump died. well once that was repaired i thought things would be ok but unfortunately the light came back on. so i don't get raped at the garage can you please help me and tell me what my problem might be and how costly it might run me?? thank you so much-- mary jo

2 oxygen sensor problem- from the very beginning fortunately the light came back on, is it still the O2 sensors? If so then its the reason why the check engine light is coming on.
