Hey All,

I have just put in my new headers a couple of weeks ago, and I'm getting a few unexpected codes.

First, the info: The headers are the ebay LT's with ceramic coating on the outside, and I'm running the rear O2 in the front on the driver's side and an LC-1 wideband on the pass. side; the rear O2's have sims in place. I originally was only getting P1134 within a few days of driving, which is for the drivers side, but now I'm also getting P1154 for the pass. side.

I have found lots of info for troubleshooting these codes, but I thought I'd throw it out to you guys for your expert advice. There are no exhaust leaks, and I pulled the LC-1 last night and it looks clean as a whistle, so I don't think there is any contamination of the sensors. Any ideas??? The car runs great, by the way.

Thanks in advance!

I dont not know if the front and rear o2's are interchangeable. I know they have a diff part number. Maybe try using correct front o2's? Maybe the left and the right are switched? Those are my guesses.

I threw the same code. I have LTs and dual cut outs just installed and when opened I threw the same code after I ran the thing hard one day.

The rear O2's are not the same as the front ones. If they are installed wrong it will throw codes.

plus a wideband I thought was for tuning the car only? maybe I am missing something.

You should have the same O2 sensors in the front. Buy the correct ones for the fronts.
