Use carb cleaner and a wire brush.
To clean the EGR valve on a 1994 Cadillac DeVille, first, disconnect the negative battery cable and remove the EGR valve from the intake manifold. Use a carburetor cleaner and a soft brush to remove carbon deposits from the valve and passages. Make sure to clean all the ports thoroughly, then reassemble the valve and reconnect it to the manifold. Finally, reconnect the battery and check for proper operation.
It usually is a carbon build up. take off egr valve, use a scraper or wire wheel to clean it, same with manifold, don't use chemicals on the valve itself, but I guess you could use brake cleaner on the port of the engine if you can't scrape it out. get a dremel tool with the long flex extension, put on a wire wheel and clean it out like that
Remove the egr valve from the tracker. The valve can be soaked with carburetor cleaner, to loosen stuck material, Wipe out loose build up, then wash with carburetor and allow to air dry. Re install the now cleaned valve.

how to clean egr valvegood question. i have a 96 lumina and am suspectful of the egr valve in mine. i read that you can at least check to see if it is stuck open/closed. how you do this i don't know. i removed what i think is my egr valve and havent tried to take it apart. i did find star bit screw on the component that i can push in without any effort (there is obviously a spring inside cuz it pushes back out) . I'm thinking that this is a good sign also cleaning out the hoses that work with the egr valve should be part of the procedure.i could use help on this too.
Yes, it is possible to clean an EGR (Exhaust Gas Recirculation) valve without removing it from the engine, though the effectiveness might be limited. You can use a specialized EGR cleaning spray or intake cleaner, directing it into the valve while the engine is running to help dissolve carbon buildup. However, this method may not reach all areas of the valve thoroughly, and for a more complete cleaning, removal is often recommended. Always follow the manufacturer's guidelines and safety precautions when attempting this.
To replace or clean the EGR valve on a 1997 Honda Civic, first disconnect the negative battery terminal and remove any components obstructing access to the valve. For cleaning, detach the EGR valve from the intake manifold and use an appropriate cleaner to remove carbon deposits. If replacing, install the new valve with a new gasket, reconnect all hoses and electrical connections, and reattach any components you removed. Finally, reconnect the battery and start the engine to ensure proper operation.
Removal Remove the air cleaner outlet tube. Disconnect the mass air flow (MAF) sensor electrical connector. Disconnect the breather pipe. Remove the air cleaner. Fully loosen the exhaust gas recirculation (EGR) valve to exhaust manifold tube nut from the bottom of the EGR valve. Disconnect the vacuum line from the top of the EGR valve. Remove the EGR valve. Remove and discard the EGR valve gasket. Installation NOTE: Use a new EGR valve gasket when installing the EGR valve. To install, reverse the removal procedure.
It is a 50 EGR Valve. You can use it for '93-'97 Dodge Dakota, Ram 1500, 2500, or Jeep.
Yes. To thin, and to clean up, you will have to use a solvent.
Through the 90's, all SC2 engines were mostly interchangeable. There was a difference in the head, requiring the use of a different EGR valve. If the replacement engine does not use the same EGR valve, it is possible to create an adapter to use the older style EGR valve.
