Guys the other night I removed my egr tube from the top of the intake for a brief couple minutes. Tonight when I started my car there seems to be air leaking from it, like a vacuum leak. I bolted in back on correctly when I removed it and my car has thrown a code. Any ideas?

 

probably needs a new o-ring around the tube where it bolts to the intake

 

Any ideas where I can find one? Autozone?

 

i bought mine at the dealership. autozone says they have one but i would get the gm one.
