CEL code P1131?

[candmforever]

My check engine light came on last night. After a little discussion with Autozone, they pulled my code P1131 and said I had to talk to the dealer to find out what it ment. Anyone know?

Fucking A, that autozone is a bunch of morons..
first of all they have a database that will tell you what that code will be.
Secondly let me look real quick.

ok it looks like a oxygen sensor is out.

I got P1130

and the description is:

Lack of h02s Switch - adaptive at fuel limit.

I am thinking of doing a dual exhaust without cats. Should I just buy some MIL eliminators? If not, How do I test which O2 sensor is out?
Thanks

I dont know which o2 sensor. I believe its one of the 02 sensors in the Headers which even if u got mil elimnators you would still have the header sensors.

So you should either get them tested at a shop, or get a multimeter and test them your self.
