Review on Original Engine Management 91007 Valve by John Huskisson

For the price this is a cheap repair. On SOHC 4.0 2004 and up as found in Explorer/Mountaineers, the DPFE sensor is an integral part of the EGR valve, so this part replaces both at the same time, hence the price increase over older EGR valves. Installation is much easier if you remove the air intake pipe and throttle body. It's only four bolts, but be sure to remove the sealed plastic gasket between the throttle body and the intake manifold, that's what the vanes are sticking out of. It's also a good idea to remove the throttle body as it will likely need to be cleaned anyway. They have no idle control and use a wire operated throttle to set the idle. If you have black mud where the butterfly closes up and down, your idle isn't going to be what it needs, and that can be code set, not to mention a rough idle and slower throttle response. Hold the butterfly open, spray on carburetor cleaner and clean. Now that those parts are out of the way, you have easy access to the first thing to remove, the exhaust pipe from the manifold to the valve. Spray it with penetrating lubricant and move it slowly and it should come off. I didn't have a problem here, but I've read about people busting their pipes. After that you can pull the vacuum lines out backwards (a rubber block) and then switch off the electrics. They have a red tab that you have to slide back before you can click the little tab in the middle to disable it. If you forget to slide this tab back, it will be very difficult for you to disconnect. Remove the 8mm bolts with a 1/4" deep head ratchet and you can easily do both while standing on the passenger side. Don't forget the small metal spacer or it will fall into the air intake. Conversely, to install new and old, no more low flow EGR codes. The reason for my 4 star rating is the packaging. My new metal gasket was folded in half and unusable. I had to reuse my old one but it works fine. I will update if this part dies prematurely. Much luck!
