I bought some Casper 02 sims and i set an ses light tonite, i installed them with my off-road y-pipe the other day. Havent had the the code read yet, but will do it first thing tomorrow, im pretty sure its related to the sims, car runs perfectly fine. Why wouldnt they work.

 

Just bought these from summit, any ideas?

 

You're blaming them before you even have the code read. It's kinda futile to try to diagnose a problem you might have.

 

Shoebox,
You were correct, not to o2 smis, its a po400, looks like im gunna need a computer programming for the ORP.

 

Ahhh P0400...looks like you may be interested in the EGR simulator to cure this problem. I just made mine the other day...works well so far...let me know if you want instructions to make it.

 

If you dont mind shoot me what info you have on the egr sim to jared_1181@hotmail.com or you can PM. I saw that post when i did a search, do you have part numbers and stuff?
