Removed EGR now have problems

[vex]

Okay, so I went ahead and pulled the Upper intake manifold off to repair a fuel line that had decided to rupture. While I had it off I went ahead and removed the EGR and put the block off plate on. I went to start it up and it won't stay on. The NB reads 0 volts, which I think is lean, even while cranking and idling. Temperature and everything else seems normal. The plugs were a little fouled but nothing beyond normal. I haven't changed anything on the car besides those fuel lines. There were no electrical problems before. The only difference between now and the last time it ran is the temperature. (upper 40's to low 30's now)

What I'd like to know is if my removing the EGR if the low temperature would keep it from keeping a proper idle? It was running spectacular for about 30 seconds while I drove it around, then after that I pulled up to a stop sign and it stalled out on me.

Any suggestions?
