91 lincoln towncar egr problem

How do you test the evaporative emissions control valve? I have changed the egr valve and the tubing to the exhaust. Still getting control valve malfunction code. Any ideas?

What are the codes? Did you check your DPFE sensor yet? And check for vacuum leaks?

Yep DPFE valve stands for delta pressure feed back exhaust.

How do you check the DPFE? I have checked for leaks and found none.:mad: This thing is driving me nuts!

I also changed the control valve....no change.

Try this, spray carb cleaner around the 2 rubber hoses that come from the EGR pipe to the DPFE sensor and see if that make a change in the engines idle
