Their is an EGR back preasure transducer on most ford engines. And they do go bad. Most of the EGR valves replaced are perfectly GOOD. And the solenoids rarely go bad. Check the transducer by replacing it. That is the only way it can be tested by a lay person. Good Luck Tom
HAVE YOU DRIVEN A FORD LATELY!!!
