Hi I changed my egr valve today and the one I picked up from Autozone has a hole that I never seen before on the side of it? The new one makes the truck run worse because of the hole... It just pushs air out like an exhaust leak. Any thoughts or anyone know why that hole is there?

I have bought two EGR valves recently, and both came with a little metal plate that you secure over that hole.
 






Here you can see a picture of it. The plate is the little silver thing, next to the black screw in this pic:

You fit the big end of the silver plate in the big hole, and then screw in the little black screw. That holds the plate in place.
 






I returned that valve and bought one for 95 and it didn't have the hole. Easier than trying to find the damn cover
 






Was doing work on my mother's Mercury. Ran into the same situation. Ya just don't think about them not including a new plate. Nor do you think, once you notice, that you won't get that old plate off because it has become one with the EGR valve. My brother stopped by as this was going on (he was fixing her roof), we had a drink, then we had a solution after he tried to get the old plate. Tap qnd die, put a bolt in the hole (not a long one, just plug the hole). Worked like a charm.
 






I'm not sure what the extra holes are for, but I can guess they are for other vehicles, that may have an extra vac connection or sensor connection there.
 






Question: The vacuum hoses on that EGR pipe connect to where? Mine do not look right.

They connect to the DPFE sensor, located right above the tube area.

I can't look at my truck at the moment but off memory:
The topmost vac fitting on the tube goes to the driver's side of the DPFE sensor (the DPFE Sensor is a rectangular shaped "box" with two vac lines and an electrical connector) vac port.

The bottomost vac fitting on the tube goes to the passenger side DPFE sensor fitting.

I *might* have that reversed, but you can tell by the size of the vac ports (one is bigger than the other).
