Okay. First question:
Is the SPOUT connector plugged in?
Second, do you still have the evap container hooked up?
The vacuum hose that goes to the EGR valve is probably damaged. Inspect it very closely for cracks or tears, and obstructions.
If the hose is good, start the engine with a vacuum pump attached to the EGR, and apply 10" of vacuum. The engine should either stall, or stumble heavily. If it doesn't, replace the EGR valve.
Do/answer these, and we'll go from there.
Take care,
