Inspect the EGR valve function with the engine running at stabilized engine temperature as follows:
1. Plug the tailpipe with a socket allowing approximately a 1/4-inch opening to permit some of the exhaust gas to escape.
2. Disconnect the EGR valve vacuum source hose and attach a hand vacuum pump to the valve. With the engine idling, apply eight inches of vacuum to the EGR valve. The engine idle speed should decrease noticeably.
3. Stop the engine and remove the socket from the tailpipe.
4. If the idle speed did not decrease, replace the EGR valve.
