I have had to clean the EGR Valve on my 1999 Honda Accord EX V6 twice (Check engine light told me it was low EGR flow). Once at 160 k miles and I just did it again at 260,000 miles. In both cases it was NOT the EGR valve itself, but the small path from the EGR valve up to the intake manifold that was blocked solid with black carbon. the channel narrows down right at the base of the intake manifold block. To unplug it: Remove the plastic coverings on top of the intake mainfold. Then remove the ~6-8 bolts that hold down the intake manifold on top of the engine. Tilt the intakemanifold up (I left the air intake hose and throttle body attached). There was a small channel (about 1/4" wide) on the underside of the intake manifold a few inches from where the hose attaches. Use a coat hanger, small screwdriver, and/or test tube brush to dig or scrape out the built-up black carbon. (FYI-- since the EGR valve is pretty easy to remove, I'd suggest pulling it 1st to see if there is anything plugged there--- mine had soot, but was relatively clear

How do you replace an EGR valve on a 91 Saturn sc?
Open the hood, look down at the engine. There is a little round device on the right side of the engine, just above the transmission bell housing. That's the EGR valve. Unplug the connectors and any vacuum lines (depending on type) then remove the two bolts and the EGR valve should come right out. Put the new one in in reverse order. BTW, an erg is a dyne centimeter squared. An EGR valve is an Exhaust Gas Recycling valve. Quite different concepts.

What is the egr valve for in 91 wrangler?
The EGR (exhaust gas recirculation) valve redirects exhaust gases back to the intake manifold and cools the cylinders down. On something that old, it's probably vacuum operated. A vacuum line going into the top of the valve pulls up a pintle. One side of the valve has a hose from the exhaust, and the other side goes to the intake.
