So I just installed headers, removed the cats, now my yukon hangs when I rev the engine. I had to remove the drivers side head because of a broken stud, pretty sure I put everything back in the right place. Did I forget to I stall something? I did install restrictors on the rear o2 sensors. What did I do wrong?
