On the elbow attached between the upper intake manifold and throttle body.

Re: Egr info

I believe they are located in the passenger's side rear corner of the engine bay.
Maybe behind the inner fender.

Not sure. Since there are wiring connectors attached to some of them it may cause issues with your ECU.
Usually when removing the EGR, most people use an EGR Eliminator (Search the forums for more info on them.) to fool the ECU into thinking it is still there so it does not throw a CEL.
The wiring connections and a vacuum source to those parts may be necessary in doing that.

From idle pressure? Yes

Yes it is.
Just like when you turn on a faucet or open a valve on any pressurized container.

Ok I was just wandering cuz my car has devolped a miss only if I push down on the gas pedel more thsn half throttle when I driving it. When I rev it it does fine . Almost like a hicup. Don't do it if I'm easy on it. Amd I've done put a new tune up. New fuel filter.new distubitor Checked the voltages on the maf and tps. Haven't tried the fuel pump or oxygen sensors but ain't getting no codes. It seems like a fuel problem to me. Cause it seems like if I try to give it alot of gas at one time it won't take it and miss. But I guess i'm going to try a new pump when I get alittle extra money. But the egr is capped off from the header but it missed b4 I capped it off so I'm just runnig out of things to try. But hopefully the pump will take care of it

could be a spark issue as well.new plugs and coil might help as well.

New coil IMO always helps with throttle response and they are relatively cheap.should be part of a tune up if it is old.AutoZone sells msd.
