Engine Performance problem
2000 Ford Crown Victoria V8 Two Wheel Drive Automatic
I am getting an egr code on my check engine. The egr vacuum control regulator has line voltage and 36 ohms. This is in range. The dpfe has 5.2 volts. This is in range. I removed the egr valve. It did not have any significant build up. When I applied a vacuum (with my mouth) the valve opened and closed properly. When I put it all back together, the check engine light came back on after about twenty minuets driving time. What am I overlooking?
Thanks for the help,
