it's an O2 sensor, either a loose connection or not working at all...they said that it could make my engine run lean or rich do you know which one cobras typically go to for something like this

the code is P1151 and P0151, which i just read is a lean running cylinder bank, GREAT, and a low voltage reading to the O2 sensor

well, i have an O/R X pipe, so without a chip or tune or MIL eliminators my check engine light will come on (basically throwing the same codes as yours). some people are able to just put on some MIL elims and be done with it (light wont come back on) but i had to get a chip to tell my computer not to worry about it.

maybe check your O2 sensors and connections, located around the bend after your headers. they screw into your exhaust pipes. i would check the connections and maybe take them out to see if the holes are all clogged up. you may just need to replace them.... or get a chip/tune!

Your front 02 sensor on left and right (closest to the header) are going out. Just replace it. Kinda time consuming but just take your time

I would just check to make sure that wires are conn. and not broken.Then just reset the light to see if it comes back on.Remember auto zone will reset it for you.
