Q:
What is the location and common issue with the EGR valve for Buick Skylark,Oldsmobile Omega and Pontiac Phoenix? Posted by Customer
A:
The EGA valve is located on the intake manifold, adjacent to the carburetor. Most of the time, when a fault develops in this emissions system it is due to a stuck or corroded EGA valve. To check the valve, with the engine cold to prevent burns, reach under the EGA valve and manually push on the diaphragm. Using moderate pressure, you should be able to press the diaphragm up and down within the housing. If the diaphragm does not move or moves only with much effort, replace the EGA valve with a new one. If you are in doubt about the quality of the valve, go to your local part store and compare the free movement of your EGA valve with a new valve.
