Quite easily take off the air breather tube then there is a cone shaped part with a connector on top at the back of the engine right by the accelerator cable 2 10mm bolts hold it on take off the 2 bolts and the valve comes off. If your still not sure you can buy a new EGR valve or if your going to just clean it to save you some money, you can use Carb cleaner which you can get at Auto Zone and they can give you the step by step instruction's free of charge to replacing the EGR valve on you car with common tools. Good luck

Remove the plugs, make sure the new plugs are gapped to .040, put anti-seize on the threads of the new plugs, then install them and tighten accordingly.

Check for intake manifold leaks and carbon in EGR pipe and EGR.
====
Check for
vacuum leaks on intake manifold,
the air tube between the air filter.
intake manifold vacuum hose.
===
clean throttle plate with Berryman carburator cleaner
SEE sample picture HERE
===
Also remove carbon built up behind the EGR valve and the EGR passage tube.
===
Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.
More un-metered air (leaks) will lean out the fuel mixture.
Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.
At idle,just spray and listen for the RPM surge.
The in-rush of carb clearer will increase the RPM on the motor.
Record the problem spot(s) and address it later.
===
EGR carbon built up require 2+ hours to clean from start to finish.
You will need a new EGR base gasket before your start.
Locate and remove the EGR valve after the vehicle is cool down.
Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.
Remove the EGR valve.
Inspect the location of the carbon built-up inside the valve and the EGR passage tube.
SOAK these areas with WD-40 spary.
You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.
RE-SOAK the carbon and let it sit for over-night will also help.
One the last round,pass a shop vacuum of the EGR valve and the passage pipe.
Install the new EGR gasket and connectors.
Allow the vehicle to warm up outdoor to burn up any remaining WD-40.
Take it for a test drive.
Please rate my answer if it's useful to you.

SOURCE: where is the egr valve
as your standing in front of the car it will be to the right of the valve cover near where the upper hose goes into the head. It should have 3 or 4 wire going to it. If you search an online parts store they will show you a picture of what it looks like.
