Replaced the egr value on a 1993 gmc Sierra still doing the same thing any suggestions

Check that the EGR vacuum solenoid is working. Remove the vacuum line to the EGR and there should be no vacuum in that line with the engine at idle.

Where is the egr valve located on my 1995 gmc sierra 1500 4.3 eng?

The EGR is typically put behind and under the air cleaner on the passenger side, it is between the distributor and the throttle body. The EGR is mounted to the intake manifold by two bolts and remove the rubber vacuum line.
Must use correct sealing gasket.

Where is my EGR valve on my 99 GMC Sierra loceted?

If it is so equipped, its located on the back side of the engine. Just to the left of the Intake manifold. You can trace the pipe running from the passenger side exhaust manifold up to it. It is a small roundish steel canister with a wiring plug and vacuum line attached.
