On older Fords ('95 and older), a simple block off plate is used in place of the EGR and the tube that goes to the exhaust manifold welded shut or a threaded plug is used to replace the exhaust tube fitting. Newer Fords (like my '97) will require the connector that's on top of the EGR valve have a few resistors spliced in to 'trick' the ECM into thinking the EGR is still in place. Otherwise, you can leave the EGR valve on and the connector plugged in and just block off the tube. On my F350, a quarter fits nicely inside the nut that holds the exhaust tube to the EGR valve and the exhaust manifold. Just removed the tube and filled the open holes inside the tube-nut with a quarter and put the nut back on the exhaust manifold and EGR valve.
On your Mountaineer what P code is showing up?
The Air Injection Pump can be deleted several ways. On my F350, I had to physically remove the pump because a shorter belt wouldn't fit without removing the pump. But removing the pump would change how the belt was routed and the tensioner would no longer work. This required a few other changes. First, I had to use an alternator bracket for a 302. The 302 bracket relocated the belt tensioner to the correct location. Then I had to swap out the alternator for one used on a 460 (so it was clocked correctly). And I still had to make a small bracket to secure the top of the alternator. An easier way is to just stuff short pieces of wood dowel into the rubber hoses that go the exhaust manifolds. Can't say off the top of my head what you would need to do to remove it on your 302. If your accessory drive on your 302 powered Mountaineer is the same as 302 powered Mustangs, there are ready made kits to delete the air pump.

It was replaced in 1998 by the 4R100. all of the differences were internal and the 4R100 would probably help fuel economy a small amount. The biggest difference between the E4OD and the 4R100 are the gear ratios. Most of the 4R100 parts will swap into the E4OD case.
