Well i did headers not to long ago, and now i get an ses light after 10 min. of driving, but if i turn the car off and then back on, it goes away for another 10 min. I got it scanned and they said that both of the O2's were reading the same and not changing. My car had four Os's but i deleted the rear two. Does anyone know what the connectors look like for the front and the back O2's ? maybe i hooked up the wrong ones...i dont know. thanks in advance for any help

 

When you "deleted" the rear O2's, did you install "sims" to make the PCM think they are still there, or did you have the rear sensors "programmed out" of the PCM?

 

I did the obd1 conversion so they are not in the pcm. no sims needed.

 

My mistake.

Sorry

 

my fault i didnt say that before...thanks for the time
