EGR valve is on the back of the engine by the firewall. take off the air cleaner completely and then look down the back of the engine and you will see a round object with an elogated egg shaped base with 2 nuts holding it on. I replaced mine and my gas mileage went up to 26-27 miles to the gallon
The EGR valve is directly under the hood on the 89 Cavalier.
The 1989 Honda Civic is not equipped with an EGR valve.

The round black object sitting bolted to the back of the throttle body. Entwined in the fuel lines; difficult to remove. If all else fails follow your tiny vacuum hose from the vrv valve.
Pluged air filter, oxygen sensor is bad, bad catlitic converter. A tune up can help. Use the cheap gas it has less hydrocarbons in it Check the EGR valve. It might be plugged up with carbon. The EGR valve allows exhaust gas to be recirculated back into the engine and if it is plugged up, this doesn't happen. The EGR valve is to control the NOx emissions.
On the V-6 it is directly behind the carburetor, the Delphi model consists of 2 parts, the EGR valve that mounts into the intake manifold and an electronic assisted switch component that attaches to the hoses above it. You can't order the electric switch separate, comes as a complete unit, approx $89.
Try your throttle body gasket...before the IAC ;) NEW ANSWER: The most common cause of that is the EGR VALVE. Check it first and make sure it is working right.
