Joe, you've done a great job with video clips and pictures, but without actually being there, I'm half blind too. Could be a problem with your 10 pin, but I can't glance at that. Know what I mean?

Okay, here's the "by the book" way to check your egr:

1) Disconnect Idle Air Bypass valve
2) Disconnect and plug hose at EGR
3) Connect a hand vacuum pump to the EGR
4) Start engine.
5) Apply 5-10" to vacuum hose

If engine becomes unstable or engine stalls, EGR valve is functioning properly.

6) Reconnect idle air bypass connector.
7) Connect vacuum pump toEGR vacuum supply hose
8) Ensure engine is at normal operating temp.
9) Start engine and increase idle speed to 1500-2000 rpms.

Vacuum gauge on pump should read 5". If it doesn't, you have a problem. If it does, the EGR system is fine.

Take care,
