Hey guys! Sorry for the late reply. So I caved in after replacing both o2 sensors. I took the car to a specialized mechanic that only works with GM cars. He ran a complete diagnostics just to find a short. The insulation around my oil pan was worn out and a wire was touching. Codes are fixed, o2 sensors were still good, and I'm out a few hundred bucks. I should've just taken it in when I first got the codes. Still didn't hurt to replace those though. You live and you learn, right? Thank you guys for all of your help. I took about ten pictures, I'll post a walkthrough on how to replace both o2 sensors when I get some free time. Anyways, take it easy guys!

What wire?? I am having the same issue with the fuse that keeps blowing

My 06grand prix gxp has been kicking out a gross evap leak. I have found where there is a place on the intake manifold where a hose should plug in but there isn't a hose there. It's right after the throttle body and points towards the firewall. I think a hose not being connected here is what's throwing my code. Any ideas on what that tube sticking off the manifold by my TB is for?

It goes to nothing. Your best bet is make sure the line isn't damaged going to the rear of the car to the fuel tank

I know this is a old thread. I just had to add that the information about the shorted wire around the oil pan on the passenger side was same for me as well.
My Grand Prix kept blowing fuses even after I unplugged all O2 sensors and the evap purge. I read the where the mechanic found the short so, I looked and found the my short in this area as well. Good Info.
