egr checking

[William Magliocco]

Have changed most of the rubber lines, checked the EGR
valve for some level of operation, etc.

Drove around tonight, pulling off the modulated vacuum
line to the EGR valve.  After some driving, got a 2411
blinky light code (EGR trouble)...once on the light
latched on until I replaced the hose onto the valve
assembly.

Tried the same thing with the plug to the EGR
frequency modulating solenoid.  The software caught
that one immediately, same trouble code.

Any advice???  Really gotta get to the bottom of this.
 Hopefully an IR thermometer will make itself
available tomorrow.
