Isn't that the EGR pipe?!!! Supposed to have 2 ports that have vacuum hoses that run into the 2 ports at the bottom of the DPFE sensor! You can see in the pic the DPFE sensor "metal block" with brown, yellow, white wires connected to the plug. Did they forget to put them back on when your headers were installed?!!!!!!!!!!!! Elky all Contours have them. LOL! No wonder your car runs like ass Goonz!
See pic!
