Found what I was looking for: Its called a smog pump, thats why I couldn't find it. Motorcraft is the only aftermarket company that makes it, I believe. The bad boy set me back $191.00, hopefully it will pass now.
Anyone know what this is? I found out mine is reading wrong and I have no idea even where it is. Also does anyone know where a electronical schematic is for a 2000 mustang?
