I recently installed an offroad H, and i threw a set of MIL Eliminators on as well. Since then my engine light has been comming on, and while i dont have a code scanner, but im fairly certain it is because of one of the O2 sensors. Originally i had forgotten to plug in the front 02 so i fixed that then unplugged the batt. to reset it. After about another 20 miles of driving it came back on, but i cant find anything wrong this time. Im pretty sure i have the mil eliminators hooked up right... O2 sensor harness plugs into one end, and the harness on the car plugs into the other end, right? Any ideas??

Also... when i installed the mil eliminators, one of them didnt fit right. The pins are correct, but the plastic grooves didnt match up on one of them, so i ground them down, and it fits snuggly now. Im not sure if that has anything to do with my problem because the pins line up correctly now and it fits snuggly.

i had to ground the plastic tabs too.......im still waitin for extensions since the o/r x-pipe that i bought the front sensor rings are way far so i need extensions....i dunno...might be that you messed up the wires on ur 02 sensors and its not functioning right...might wanna get that checked...

yeah i guess ill go to autozone and see what the code is.

pulled the code...

P0155 O2 senseor Heater Circuit Malfunction. (Bank 2 Sensor 1). any idea which sensor that is?

EDIT: ok its one of the pre-cat sensors which is why im getting crappy mileage, but which side is Bank 2? Im guessing passenger?

have no clue...might have the same problem when i get my extensions.....i think it is passenger side...if ya got it checked somewhere...did they give ya advice how to fix it??...cuz ur prolly not the only one who needs this advice...prolly me too..

nah the guy at Autozone didnt seem like he knew much... i had to show him how the code scanner plugged in.... I bought a new 02 sensor and just got finished installing it. im going out in an hour so i'll find out then if it is fixed. I just hope i replaced the right one(im going on my assumption that bank 2 is the passenger side, but im still not sure).

Did you already buy the extensions?? I have a set here that im not using if you need them.. the sensor wires were just long enough on my '00 gt that i didnt need the extensions.
