I was drivin home the other day and my SES light came on. I got it checked out and it was

P1133: Air Fuel metering, or something along those lines

What the hell is that? and what does it involve/pertain to?
Thanks very much!

HO2S Insufficient Switching Sensor 1

Most likely your O2 is dead and you need to replace it OR your extension harness burned up on your headers.
